There is no remote or adjacent-network path into openvswitch flow-action validation.\nAC:L - Triggering requires only a single well-formed netlink message containing an OVS_ACTION_ATTR_SET whose inner nlattr declares nla_len of 1-3; there is no race, no timing window, and no dependence on memory layout the attacker cannot influence. The negative-length path is fully in-bounds and deterministic, and the actions are validated before the datapath lookup so not even a datapath must exist.\nPR:L - The OVS flow genl ops use GENL_UNS_ADMIN_PERM with .netnsok = true, so the CAP_NET_ADMIN check is scoped to the netns\u0027s owning user namespace and any unprivileged user can satisfy it with `unshare -Urn`. The openvswitch module is autoloaded from an unprivileged CTRL_CMD_GETFAMILY lookup via MODULE_ALIAS_GENL_FAMILY.\nUI:N - The attacker performs the entire sequence themselves via socket()/sendmsg(); no action by any other user or administrator is needed.\nS:U - The corruption is confined to kernel memory under the same security authority as the attacking process; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - The bug produces out-of-bounds reads beyond the netlink skb \u2014 the KMSAN-confirmed header read, the unbounded forward scan in validate_masked() with a negative length, and a memcpy whose source is read for up to SIZE_MAX bytes. Data copied out of bounds lands in the flow\u0027s actions buffer, which is echoed back to userspace by OVS_FLOW_CMD_GET/DUMP, giving an arbitrary kernel-memory disclosure primitive.\nI:H - With key_len underflowing to (size_t)-1, `memcpy(nla_data(at), nla_data(ovs_key), key_len)` and the following `memset(..., 0xff, key_len)` perform an effectively unbounded out-of-bounds write over the kernel heap using attacker-influenced data. An out-of-bounds write of this scope is a full integrity compromise.\nA:H - The wild memcpy/memset will fault as soon as it walks off mapped memory, and the negative-length validate_masked() loop scans up to 4G of memory; either way the result is a kernel panic, and on sanitizer builds it is an immediate KASAN/KMSAN report. The crash is reachable repeatedly by an unprivileged local user."

Title
KVM: arm64: Tear down vGIC on failed vCPU creation
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Tear down vGIC on failed vCPU creation
If kvm_arch_vcpu_create() fails to share the vCPU page with the
hypervisor, we propagate the error back to the ioctl but leave the
vGIC vCPU data initialised. Note only does this leak the corresponding
memory when the vCPU is destroyed but it can also lead to use-after-free
if the redistributor device handling tries to walk into the vCPU.
Add the missing cleanup to kvm_arch_vcpu_create(), ensuring that the
vGIC vCPU structures are destroyed on error.

8.8 (High)

This problem is similar to the problem that the
commit 1d6a9e7449e2 ("RDMA/core: Fix use-after-free when rename device name")
fixes.
The root cause is: the function ib_device_rename() renames the name with
lock. But in the function kobject_uevent(), this name is accessed without
lock protection at the same time.
The solution is to add the lock protection when this name is accessed in
the function kobject_uevent().

No remote peer data reaches the vulnerable code.\nAC:L - The attacker controls both sides of the race, looping RDMA_NLDEV_CMD_NEWLINK in one thread and RDMA_NLDEV_CMD_SET (rename) in another; `enable_device_and_get()` marks the device DEVICE_REGISTERED and drops to refcount 2 before the unprotected `kobject_uevent()`, leaving a reliably hittable window that syzkaller reproduced.\nPR:L - The gate is `netlink_capable(skb, CAP_NET_ADMIN)`, which checks init_user_ns and so is not obtainable via `unshare -Urn`, but CAP_NET_ADMIN in the initial user namespace is routinely delegated to non-root, container-confined workloads (Docker/K8s do not enable user namespaces by default, and RDMA/SR-IOV network plugins commonly run with `--cap-add=NET_ADMIN`). Scored as a low-privileged principal rather than real host root.\nUI:N - The attacker triggers both the device registration and the concurrent rename entirely on its own via netlink; no victim action is involved.\nS:U - The use-after-free is in kernel slab memory and its impact stays within the kernel\u0027s security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The freed `kobj-\u003ename` slab object is `strlen`\u0027d and `memcpy`\u0027d into the `DEVPATH=` uevent variable that is broadcast to userspace listeners and the uevent helper, so reallocated kernel heap contents are disclosed outside the kernel, and the unterminated `strlen` reads out of bounds past the freed chunk.\nI:H - This is a slab use-after-free where the attacker can spray the freed kmalloc chunk and control the data the kernel then consumes; per UAF-class scoring the reallocation primitive is treated as exploitable for kernel state corruption, and the resulting bogus DEVPATH also drives userspace device management onto the wrong sysfs path.\nA:H - KASAN reports a slab-use-after-free read that can fault and oops when the backing page is freed or under KFENCE/page poisoning, and `kobject_get_path()`\u0027s `retry` loop can spin under a sustained rename storm, both causing denial of service."

In the function rxe_create_cq, when rxe_cq_from_init fails, the function
rxe_cleanup will be called to handle the allocated resources. In fact,
some memory resources have already been freed in the function
rxe_cq_from_init. Thus, this problem will occur.
The solution is to let rxe_cleanup do all the work.

Title
Squashfs: check return result of sb_min_blocksize
Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check return result of sb_min_blocksize
Syzkaller reports an "UBSAN: shift-out-of-bounds in squashfs_bio_read" bug.
Syzkaller forks multiple processes which after mounting the Squashfs
filesystem, issues an ioctl("/dev/loop0", LOOP_SET_BLOCK_SIZE, 0x8000).
Now if this ioctl occurs at the same time another process is in the
process of mounting a Squashfs filesystem on /dev/loop0, the failure
occurs. When this happens the following code in squashfs_fill_super()
fails.
----
msblk->devblksize = sb_min_blocksize(sb, SQUASHFS_DEVBLK_SIZE);
msblk->devblksize_log2 = ffz(~msblk->devblksize);
----
sb_min_blocksize() returns 0, which means msblk->devblksize is set to 0.
As a result, ffz(~msblk->devblksize) returns 64, and msblk->devblksize_log2
is set to 64.
This subsequently causes the
UBSAN: shift-out-of-bounds in fs/squashfs/block.c:195:36
shift exponent 64 is too large for 64-bit type 'u64' (aka
'unsigned long long')
This commit adds a check for a 0 return by sb_min_blocksize().
Severity

Title
atm: clip: Fix infinite recursive call of clip_push().
Summary
In the Linux kernel, the following vulnerability has been resolved:
atm: clip: Fix infinite recursive call of clip_push().
syzbot reported the splat below. [0]
This happens if we call ioctl(ATMARP_MKIP) more than once.
During the first call, clip_mkip() sets clip_push() to vcc->push(),
and the second call copies it to clip_vcc->old_push().
Later, when the socket is close()d, vcc_destroy_socket() passes
NULL skb to clip_push(), which calls clip_vcc->old_push(),
triggering the infinite recursion.
Let's prevent the second ioctl(ATMARP_MKIP) by checking
vcc->user_back, which is allocated by the first call as clip_vcc.
Note also that we use lock_sock() to prevent racy calls.

Title
net/sched: mqprio: fix stack out-of-bounds write in tc entry parsing
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: mqprio: fix stack out-of-bounds write in tc entry parsing
TCA_MQPRIO_TC_ENTRY_INDEX is validated using
NLA_POLICY_MAX(NLA_U32, TC_QOPT_MAX_QUEUE), which allows the value
TC_QOPT_MAX_QUEUE (16). This leads to a 4-byte out-of-bounds stack
write in the fp[] array, which only has room for 16 elements (0–15).
Fix this by changing the policy to allow only up to TC_QOPT_MAX_QUEUE - 1.

The only prerequisite is a multiqueue netdev implementing ndo_setup_tc, which is true of essentially every hardware NIC, DSA user port, and mac80211 wlan interface.\nPR:L - Triggering requires CAP_NET_ADMIN in the target network namespace, which per kernel scoring guidance for tc/qdisc paths is rated Low rather than High. Realistic low-privilege holders include containers granted NET_ADMIN over a namespace holding an SR-IOV VF or passed-through NIC, and non-root TSN/network configuration daemons on automotive and industrial systems.\nUI:N - The attacker performs the entire operation themselves via a netlink socket write; no victim action, mount, or file open is needed.\nS:U - The corruption occurs on the kernel stack of the calling task and stays within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The bug corrupts kernel stack memory beyond the fp[] array, damaging adjacent frame state such as saved registers, the canary, or the in-flight netlink attribute iterator. Such kernel memory corruption is treated as leverageable toward information disclosure, so the higher rating is taken.\nI:H - This is an out-of-bounds write into the kernel stack frame at an attacker-selected trigger point, overwriting data the attacker was never permitted to modify. Out-of-bounds writes are rated High for integrity.\nA:H - On stack-protector kernels (the default for distro, Android, and automotive builds) the write lands on the canary region, so returning from mqprio_parse_tc_entries invokes __stack_chk_fail(), which calls panic() and brings the machine down unrecoverably. Even without the stack protector, the corrupted frame state causes a kernel oops."

Title
usb: core: config: Prevent OOB read in SS endpoint companion parsing
Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: core: config: Prevent OOB read in SS endpoint companion parsing
usb_parse_ss_endpoint_companion() checks descriptor type before length,
enabling a potentially odd read outside of the buffer size.
Fix this up by checking the size first before looking at any of the
fields in the descriptor.
Severity
No CVSS data available.
