CVE-2025-71113

A flaw was found in the Linux kernel's crypto AF_ALG subsystem. Memory allocated via sock_kmalloc() for crypto user API contexts is not zero-initialized, leaving fields with garbage values. Specifically, the 'inflight' variable can contain random data, causing af_alg_alloc_areq() to spuriously return -EBUSY errors when the garbage value is interpreted as true.

3.3 (Low)

CVE-2025-71147

A flaw was found in the Linux kernel's trusted keys subsystem. A local user could exploit a memory leak in the `tpm2_load_cmd` function, which fails to free a temporary memory allocation in certain error scenarios. This memory leak could lead to a system-wide Denial of Service (DoS) by exhausting available memory resources.

CVE-2026-31530

In the Linux kernel, the following vulnerability has been resolved: cxl/port: Fix use after free of parent_port in cxl_detach_ep() cxl_detach_ep() is called during bottom-up removal when all CXL memory devices beneath a switch port have been removed. For each port in the hierarchy it locks both the port and its parent, removes the endpoint, and if the port is now empty, marks it dead and unregisters the port by calling delete_switch_port(). There are two places during this work where the parent_port may be used after freeing: First, a concurrent detach may have already processed a port by the time a second worker finds it via bus_find_device(). Without pinning parent_port, it may already be freed when we discover port->dead and attempt to unlock the parent_port. In a production kernel that's a silent memory corruption, with lock debug, it looks like this: []DEBUG_LOCKS_WARN_ON(__owner_task(owner) != get_current()) []WARNING: kernel/locking/mutex.c:949 at __mutex_unlock_slowpath+0x1ee/0x310 []Call Trace: []mutex_unlock+0xd/0x20 []cxl_detach_ep+0x180/0x400 [cxl_core] []devm_action_release+0x10/0x20 []devres_release_all+0xa8/0xe0 []device_unbind_cleanup+0xd/0xa0 []really_probe+0x1a6/0x3e0 Second, delete_switch_port() releases three devm actions registered against parent_port. The last of those is unregister_port() and it calls device_unregister() on the child port, which can cascade. If parent_port is now also empty the device core may unregister and free it too. So by the time delete_switch_port() returns, parent_port may be free, and the subsequent device_unlock(&parent_port->dev) operates on freed memory. The kernel log looks same as above, with a different offset in cxl_detach_ep(). Both of these issues stem from the absence of a lifetime guarantee between a child port and its parent port. Establish a lifetime rule for ports: child ports hold a reference to their parent device until release. Take the reference when the port is allocated and drop it when released. This ensures the parent is valid for the full lifetime of the child and eliminates the use after free window in cxl_detach_ep(). This is easily reproduced with a reload of cxl_acpi in QEMU with CXL devices present.

CVE-2026-46116

A flaw was found in the Linux kernel's `xfrm` (IPSec framework) subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of `xfrm_state` lists. An attacker with local access could exploit this flaw by triggering specific operations, leading to memory corruption. This could cause the system to become unstable, resulting in crashes or a Denial of Service (DoS), and potentially allow for unauthorized access to sensitive information or increased privileges.

CVE-2026-53009

A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when ice_tso() or ice_tx_csum() functions fail, can lead to a double-free of a network buffer (skb). This occurs because a transmit buffer (tx_buf) may still point to an already freed buffer. If the network interface is subsequently brought down, this double-free can be triggered, potentially leading to a system crash or denial of service (DoS).

CVE-2025-71113 (GCVE-0-2025-71113)

Vulnerability from cvelistv5 – Published: 2026-01-14 15:05 – Updated: 2026-09-08 08:43

Title

crypto: af_alg - zero initialize memory allocated via sock_kmalloc

Summary

In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - zero initialize memory allocated via sock_kmalloc Several crypto user API contexts and requests allocated with sock_kmalloc() were left uninitialized, relying on callers to set fields explicitly. This resulted in the use of uninitialized data in certain error paths or when new fields are added in the future. The ACVP patches also contain two user-space interface files: algif_kpp.c and algif_akcipher.c. These too rely on proper initialization of their context structures. A particular issue has been observed with the newly added 'inflight' variable introduced in af_alg_ctx by commit: 67b164a871af ("crypto: af_alg - Disallow multiple in-flight AIO requests") Because the context is not memset to zero after allocation, the inflight variable has contained garbage values. As a result, af_alg_alloc_areq() has incorrectly returned -EBUSY randomly when the garbage value was interpreted as true: https://github.com/gregkh/linux/blame/master/crypto/af_alg.c#L1209 The check directly tests ctx->inflight without explicitly comparing against true/false. Since inflight is only ever set to true or false later, an uninitialized value has triggered -EBUSY failures. Zero-initializing memory allocated with sock_kmalloc() ensures inflight and other fields start in a known state, removing random issues caused by uninitialized data.

This resulted in the use of uninitialized\ndata in certain error paths or when new fields are added in the\nfuture.\n\nThe ACVP patches also contain two user-space interface files:\nalgif_kpp.c and algif_akcipher.c. These too rely on proper\ninitialization of their context structures.\n\nA particular issue has been observed with the newly added\n\u0027inflight\u0027 variable introduced in af_alg_ctx by commit:\n\n  67b164a871af (\"crypto: af_alg - Disallow multiple in-flight AIO requests\")\n\nBecause the context is not memset to zero after allocation,\nthe inflight variable has contained garbage values. As a result,\naf_alg_alloc_areq() has incorrectly returned -EBUSY randomly when\nthe garbage value was interpreted as true:\n\n  https://github.com/gregkh/linux/blame/master/crypto/af_alg.c#L1209\n\nThe check directly tests ctx-\u003einflight without explicitly\ncomparing against true/false. Since inflight is only ever set to\ntrue or false later, an uninitialized value has triggered\n-EBUSY failures. Zero-initializing memory allocated with\nsock_kmalloc() ensures inflight and other fields start in a known\nstate, removing random issues caused by uninitialized data."

CVE-2026-23168 (GCVE-0-2026-23168)

Vulnerability from cvelistv5 – Published: 2026-02-14 16:01 – Updated: 2026-05-11 22:01

Title

flex_proportions: make fprop_new_period() hardirq safe

Summary

In the Linux kernel, the following vulnerability has been resolved: flex_proportions: make fprop_new_period() hardirq safe Bernd has reported a lockdep splat from flexible proportions code that is essentially complaining about the following race: <timer fires> run_timer_softirq - we are in softirq context call_timer_fn writeout_period fprop_new_period write_seqcount_begin(&p->sequence); <hardirq is raised> ... blk_mq_end_request() blk_update_request() ext4_end_bio() folio_end_writeback() __wb_writeout_add() __fprop_add_percpu_max() if (unlikely(max_frac < FPROP_FRAC_BASE)) { fprop_fraction_percpu() seq = read_seqcount_begin(&p->sequence); - sees odd sequence so loops indefinitely Note that a deadlock like this is only possible if the bdi has configured maximum fraction of writeout throughput which is very rare in general but frequent for example for FUSE bdis. To fix this problem we have to make sure write section of the sequence counter is irqsafe.

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncxl/port: Fix use after free of parent_port in cxl_detach_ep()\n\ncxl_detach_ep() is called during bottom-up removal when all CXL memory\ndevices beneath a switch port have been removed. For each port in the\nhierarchy it locks both the port and its parent, removes the endpoint,\nand if the port is now empty, marks it dead and unregisters the port\nby calling delete_switch_port(). There are two places during this work\nwhere the parent_port may be used after freeing:\n\nFirst, a concurrent detach may have already processed a port by the\ntime a second worker finds it via bus_find_device(). Without pinning\nparent_port, it may already be freed when we discover port-\u003edead and\nattempt to unlock the parent_port. In a production kernel that\u0027s a\nsilent memory corruption, with lock debug, it looks like this:\n\n[]DEBUG_LOCKS_WARN_ON(__owner_task(owner) != get_current())\n[]WARNING: kernel/locking/mutex.c:949 at __mutex_unlock_slowpath+0x1ee/0x310\n[]Call Trace:\n[]mutex_unlock+0xd/0x20\n[]cxl_detach_ep+0x180/0x400 [cxl_core]\n[]devm_action_release+0x10/0x20\n[]devres_release_all+0xa8/0xe0\n[]device_unbind_cleanup+0xd/0xa0\n[]really_probe+0x1a6/0x3e0\n\nSecond, delete_switch_port() releases three devm actions registered\nagainst parent_port. The last of those is unregister_port() and it\ncalls device_unregister() on the child port, which can cascade. If\nparent_port is now also empty the device core may unregister and free\nit too. So by the time delete_switch_port() returns, parent_port may\nbe free, and the subsequent device_unlock(\u0026parent_port-\u003edev) operates\non freed memory. The kernel log looks same as above, with a different\noffset in cxl_detach_ep().\n\nBoth of these issues stem from the absence of a lifetime guarantee\nbetween a child port and its parent port.\n\nEstablish a lifetime rule for ports: child ports hold a reference to\ntheir parent device until release. Take the reference when the port\nis allocated and drop it when released. This ensures the parent is\nvalid for the full lifetime of the child and eliminates the use after\nfree window in cxl_detach_ep().\n\nThis is easily reproduced with a reload of cxl_acpi in QEMU with CXL\ndevices present."

Title

xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

Summary

In the Linux kernel, the following vulnerability has been resolved: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete KASAN reproduces a slab-use-after-free in __xfrm_state_delete()'s hlist_del_rcu calls under syzkaller load on linux-6.12.y stable (reproduced on 6.12.47, also reachable via the same code path on torvalds/master and on the ipsec tree). Nine unique signatures cluster in the xfrm_state lifecycle, the load-bearing one being: BUG: KASAN: slab-use-after-free in __hlist_del include/linux/list.h:990 [inline] BUG: KASAN: slab-use-after-free in hlist_del_rcu include/linux/rculist.h:516 [inline] BUG: KASAN: slab-use-after-free in __xfrm_state_delete net/xfrm/xfrm_state.c Write of size 8 at addr ffff8881198bcb70 by task kworker/u8:9/435 Workqueue: netns cleanup_net Call Trace: __hlist_del / hlist_del_rcu __xfrm_state_delete xfrm_state_delete xfrm_state_flush xfrm_state_fini ops_exit_list cleanup_net The other observed signatures hit the same slab object from __xfrm_state_lookup, xfrm_alloc_spi, __xfrm_state_insert and an OOB write variant of __xfrm_state_delete, all on the byseq/byspi hash chains. __xfrm_state_delete() guards its byseq and byspi unhashes with value-based predicates: if (x->km.seq) hlist_del_rcu(&x->byseq); if (x->id.spi) hlist_del_rcu(&x->byspi); while everywhere else in the file (e.g. state_cache, state_cache_input) the safer hlist_unhashed() check is used. xfrm_alloc_spi() sets x->id.spi = newspi inside xfrm_state_lock and then immediately inserts into byspi, but a path that observes x->id.spi != 0 outside of xfrm_state_lock can still skip-or-hit the byspi unhash inconsistently with whether x is actually on the list. The same holds for x->km.seq versus byseq, and the bydst/bysrc unhashes have no predicate at all, so a second __xfrm_state_delete() on the same object writes through LIST_POISON pprev. The defensive change here: - Use hlist_del_init_rcu() instead of hlist_del_rcu() on bydst, bysrc, byseq and byspi so a second deletion is a no-op rather than a write through LIST_POISON pprev. The byseq/byspi nodes are already initialised in xfrm_state_alloc(). - Test hlist_unhashed() rather than the value predicate for byseq/byspi, so the unhash decision tracks list state rather than mutable scalar fields. Empirical verification: applied this patch on top of v6.12.47, rebuilt, and re-ran the same syzkaller harness for 1h16m on a previously-crashy configuration that produced ~100 hits each of slab-use-after-free Read in xfrm_alloc_spi / Read in __xfrm_state_lookup / Write in __xfrm_state_delete. After the patch, 7.1M execs across 32 VMs at ~1550 exec/sec produced zero xfrm_state UAF/OOB hits. /proc/slabinfo confirms the xfrm_state slab is actively allocated and freed during the run (~143 KiB resident), so the fuzzer is still exercising those code paths -- they just no longer crash. Reproduction: - Linux 6.12.47 x86_64 + KASAN_GENERIC + KASAN_INLINE + KCOV - syzkaller @ 746545b8b1e4c3a128db8652b340d3df90ce61db - 32 QEMU/KVM VMs x 2 vCPU on AWS c5.metal bare metal - 9 unique signatures collected in ~9h, all within xfrm_state lifecycle

CVE-2026-46215 (GCVE-0-2026-46215)

Vulnerability from cvelistv5 – Published: 2026-05-28 09:40 – Updated: 2026-08-05 12:30

Title

drm: Set old handle to NULL before prime swap in change_handle

Summary

In the Linux kernel, the following vulnerability has been resolved: drm: Set old handle to NULL before prime swap in change_handle There was a potential race condition in change_handle. The ioctl briefly had a single object with two idr entries; a concurrent gem_close could delete the object and remove one of the handles while leaving the other one dangling, which could subsequently be dereferenced for a use-after-free. To fix this, do the same dance that gem_close itself does. (f6cd7daecff5 drm: Release driver references to handle before making it available again) First idr_replace the old handle to NULL. Later, if the prime operations are successful, actually close it. create_tail required a similar dance to avoid a similar problem. (bd46cece51a3 drm/gem: Fix race in drm_gem_handle_create_tail()) It idr_allocs the new handle with NULL, then swaps in the correct object later to avoid races. We don't need to do that here, since the only operations that could race are drm_prime, and change_handle holds the prime lock for the entire duration. v2: cleanups of error paths

CVE-2026-52950 (GCVE-0-2026-52950)

Vulnerability from cvelistv5 – Published: 2026-06-24 16:28 – Updated: 2026-08-05 12:31

Title

drm/xe/dma-buf: fix UAF with retry loop

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/xe/dma-buf: fix UAF with retry loop Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init do the alloc for us. This should make the retry safe. Reported by Sashiko. v2: Fix up the error unwind (CI) (cherry picked from commit 479669418253e0f27f8cf5db01a731352ea592e7)

CVE-2026-52976 (GCVE-0-2026-52976)

Vulnerability from cvelistv5 – Published: 2026-06-24 16:28 – Updated: 2026-08-10 12:05

Title

drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl()

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl() Two error handling issues exist in xe_exec_queue_create_ioctl(): 1. When xe_hw_engine_group_add_exec_queue() fails, the error path jumps to put_exec_queue which skips xe_exec_queue_kill(). If the VM is in preempt fence mode, xe_vm_add_compute_exec_queue() has already added the queue to the VM's compute exec queue list. Skipping the kill leaves the queue on that list, leading to a dangling pointer after the queue is freed. 2. When xa_alloc() fails after xe_hw_engine_group_add_exec_queue() has succeeded, the error path does not call xe_hw_engine_group_del_exec_queue() to remove the queue from the hw engine group list. The queue is then freed while still linked into the hw engine group, causing a use-after-free. Fix both by: - Changing the xe_hw_engine_group_add_exec_queue() failure path to jump to kill_exec_queue so that xe_exec_queue_kill() properly removes the queue from the VM's compute list. - Adding a del_hw_engine_group label before kill_exec_queue for the xa_alloc() failure path, which removes the queue from the hw engine group before proceeding with the rest of the cleanup. (cherry picked from commit 37c831f401746a45d510b312b0ed7a77b1e06ec8)

When xe_hw_engine_group_add_exec_queue() fails, the error path jumps\n   to put_exec_queue which skips xe_exec_queue_kill(). If the VM is in\n   preempt fence mode, xe_vm_add_compute_exec_queue() has already added\n   the queue to the VM\u0027s compute exec queue list. Skipping the kill\n   leaves the queue on that list, leading to a dangling pointer after\n   the queue is freed.\n\n2. When xa_alloc() fails after xe_hw_engine_group_add_exec_queue() has\n   succeeded, the error path does not call\n   xe_hw_engine_group_del_exec_queue() to remove the queue from the hw\n   engine group list. The queue is then freed while still linked into\n   the hw engine group, causing a use-after-free.\n\nFix both by:\n- Changing the xe_hw_engine_group_add_exec_queue() failure path to jump\n  to kill_exec_queue so that xe_exec_queue_kill() properly removes the\n  queue from the VM\u0027s compute list.\n- Adding a del_hw_engine_group label before kill_exec_queue for the\n  xa_alloc() failure path, which removes the queue from the hw engine\n  group before proceeding with the rest of the cleanup.\n\n(cherry picked from commit 37c831f401746a45d510b312b0ed7a77b1e06ec8)"

              "value": "AV:L - The vulnerable code is reached through the local DRM Xe `XE_EXEC_QUEUE_CREATE` ioctl on a GPU device/render node. It is not reachable by remote network traffic or adjacent/physical input.\nAC:L - The attacker controls the ioctl sequence and can drive the relevant error cleanup paths through local resource pressure or interruptible operations. No uncontrollable race or rare victim state is required for the dangling queue pointer to be created and later exercised.\nPR:L - The ioctl is registered with `DRM_RENDER_ALLOW`, with no root, DRM master, or authentication requirement, so an unprivileged local GPU client that can open the render node can reach it. This is basic local user access, not real administrator privilege.\nUI:N - Exploitation only requires the attacker to issue ioctls from their own process. No victim user action is needed.\nS:U - The bug is within the kernel DRM Xe driver and impacts kernel resources under the same OS security authority. It does not cross a VM, hypervisor, or IOMMU security boundary by itself.\nC:H - The cleanup bug leaves a freed `struct xe_exec_queue` linked into VM or hardware-engine-group lists, creating a use-after-free. Under the required kernel scoring guidance, UAF memory corruption is treated as enabling high confidentiality impact.\nI:H - The stale list entry is later dereferenced through queue fields and operation pointers, making this kernel heap use-after-free potentially exploitable for control-flow or memory corruption. Under the required guidance, UAF implies high integrity impact.\nA:H - The dangling pointer can be reached by later VM or engine-group list traversal and can cause kernel oops, panic, or hang. A local attacker can trigger the condition repeatedly, so availability impact is high."
