Title
Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()
l2cap_le_flowctl_init() can cause both div-by-zero and an integer
overflow since hdev->le_mtu may not fall in the valid range.
Move MTU from hci_dev to hci_conn to validate MTU and stop the connection
process earlier if MTU is invalid.
Also, add a missing validation in read_buffer_size() and make it return
an error value if the validation fails.
Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a
kzalloc failure and invalid MTU value.

Title
net: bridge: xmit: make sure we have at least eth header len bytes
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: xmit: make sure we have at least eth header len bytes
syzbot triggered an uninit value[1] error in bridge device's xmit path
by sending a short (less than ETH_HLEN bytes) skb. To fix it check if
we can actually pull that amount instead of assuming.
Tested with dropwatch:
drop at: br_dev_xmit+0xb93/0x12d0 [bridge] (0xffffffffc06739b3)

Triggering it requires local injection of a sub-14-byte skb (tun write or AF_PACKET on a `hard_header_len == 0` device, plus a tc `mirred` redirect).\nAC:L - The attacker fully and deterministically controls the skb length; there is no race, no timing window, and no dependence on memory layout or victim state. Every attempt reaches the uninitialized read and the subsequent `skb_push()` leak.\nPR:L - The setup needs CAP_NET_ADMIN/CAP_NET_RAW only within a network namespace, which any unprivileged user obtains via `unshare -Urn` (create the bridge, create the tun/tunnel device, attach the tc mirred redirect, and capture leaked frames from a veth peer). No real root in the initial namespace is required.\nUI:N - The attacker performs every step \u2014 creating the devices, writing the short frame, and reading the leaked frames back \u2014 with no action by any other user or administrator.\nS:U - The uninitialized read, the malformed skb, and the resulting disclosure all stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 14 bytes of uninitialized kernel heap (skb headroom and the region past `skb-\u003etail`, which routinely holds freed packet data and kernel values) are read and then, via the unconditional `skb_push(skb, ETH_HLEN)` in `br_dev_queue_push_xmit()`, transmitted verbatim out every bridge port where the attacker captures them. The leak is repeatable at packet rate, yielding an effectively unbounded kernel memory disclosure rather than a bounded few-byte read.\nI:L - There is no out-of-bounds write primitive, but the kernel emits malformed frames whose source/destination MAC addresses are uninitialized memory, and forwarding decisions (broadcast/multicast/unicast, FDB lookup) are made on that garbage \u2014 corrupting local and peer bridge/switch forwarding state in a limited, attacker-influenced way.\nA:H - When the short skb has less than ETH_HLEN of headroom (as in the syzbot BPF-redirect reproducer), `skb_push(skb, ETH_HLEN)` in `br_dev_queue_push_xmit()` drives `skb-\u003edata` below `skb-\u003ehead` and hits `skb_under_panic()` \u2192 `BUG()`, a hard kernel panic. Additionally the resulting skb has `mac_header`/`network_header` desynchronized from `skb-\u003edata`, propagating a malformed skb into the generic xmit path (e.g. the `WARN_ONCE` in `skb_checksum_help()`, fatal under `panic_on_warn`), and the trigger can be repeated indefinitely."

Title
RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt
In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the
resp_pkts queue and then a decision is made whether to run the completer
task inline or schedule it. Finally the skb is dereferenced to bump a 'hw'
performance counter. This is wrong because if the completer task is
already running in a separate thread it may have already processed the skb
and freed it which can cause a seg fault. This has been observed
infrequently in testing at high scale.
This patch fixes this by changing the order of enqueuing the packet until
after the counter is accessed.

RoCEv2 is routable IP/UDP traffic, so the attacker is not confined to the local L2 segment.\nAC:L - The attacker controls both sides of the race: the vulnerable counter access only occurs when resp_pkts already holds another packet (queue_len \u003e 1), a condition created by bursting response packets while the completer work item concurrently drains and kfree_skb()s them on another CPU. The commit describes it triggering under high packet load, which is exactly what an attacker-driven flood produces.\nPR:N - RoCEv2 provides no authentication; the only checks before the UAF are QPN lookup, QP state, source/destination IP matching the QP\u0027s address vector, default pkey, and a plain CRC32 ICRC that any attacker can compute. A malicious or compromised RDMA peer, or an attacker spoofing the peer\u0027s source address, needs no credentials on the target system.\nUI:N - Exploitation requires only that the target have an active RC/UC queue pair in RTS state, which is the normal steady-state operating condition of an RDMA connection. No action by any local user or administrator is needed at attack time.\nS:U - The use-after-free corrupts kernel slab memory and is exploited within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed skb\u0027s control block is read after kfree_skb(), so the attacker can groom the reallocated slab object to source the rxe pointer, and a use-after-free on the skb slab is a classic primitive for leaking adjacent kernel memory and defeating KASLR.\nI:H - The stale pointer read from the freed object is immediately passed to rxe_counter_inc(), which performs atomic64_inc(\u0026rxe-\u003estats_counters[index]) \u2014 a write through an attacker-influenceable pointer, giving a targeted 64-bit increment primitive that can corrupt arbitrary kernel structures and be escalated to control-flow hijack.\nA:H - The commit explicitly reports a segmentation fault (kernel oops) from this dereference, and any unresolved use-after-free of an skb reliably crashes or panics the kernel, which a remote attacker can trigger repeatedly."

Title
RDMA/hns: Fix UAF for cq async event
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix UAF for cq async event
The refcount of CQ is not protected by locks. When CQ asynchronous
events and CQ destruction are concurrent, CQ may have been released,
which will cause UAF.
Use the xa_lock() to protect the CQ refcount.
Severity
7.8 (High)

Title
riscv: prevent pt_regs corruption for secondary idle threads
Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv: prevent pt_regs corruption for secondary idle threads
Top of the kernel thread stack should be reserved for pt_regs. However
this is not the case for the idle threads of the secondary boot harts.
Their stacks overlap with their pt_regs, so both may get corrupted.
Similar issue has been fixed for the primary hart, see c7cdd96eca28
("riscv: prevent stack corruption by reserving task_pt_regs(p) early").
However that fix was not propagated to the secondary harts. The problem
has been noticed in some CPU hotplug tests with V enabled. The function
smp_callin stored several registers on stack, corrupting top of pt_regs
structure including status field. As a result, kernel attempted to save
or restore inexistent V context.
Severity
No CVSS data available.

Title
9p: add missing locking around taking dentry fid list
Summary
In the Linux kernel, the following vulnerability has been resolved:
9p: add missing locking around taking dentry fid list
Fix a use-after-free on dentry's d_fsdata fid list when a thread
looks up a fid through dentry while another thread unlinks it:
UAF thread:
refcount_t: addition on 0; use-after-free.

Freed by:

p9_client_clunk+0xb0/0xe0 linux/net/9p/client.c:1456

vfs_unlink+0x29a/0x810 linux/fs/namei.c:4335
The problem is that d_fsdata was not accessed under d_lock, because
d_release() normally is only called once the dentry is otherwise no
longer accessible but since we also call it explicitly in v9fs_remove
that lock is required:
move the hlist out of the dentry under lock then unref its fids once
they are no longer accessible.

Title
ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry()
xattr in ocfs2 maybe 'non-indexed', which saved with additional space
requested. It's better to check if the memory is out of bound before
memcmp, although this possibility mainly comes from crafted poisonous
images.

Title
gfs2: Fix NULL pointer dereference in gfs2_log_flush
Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix NULL pointer dereference in gfs2_log_flush
In gfs2_jindex_free(), set sdp->sd_jdesc to NULL under the log flush
lock to provide exclusion against gfs2_log_flush().
In gfs2_log_flush(), check if sdp->sd_jdesc is non-NULL before
dereferencing it. Otherwise, we could run into a NULL pointer
dereference when outstanding glock work races with an unmount
(glock_work_func -> run_queue -> do_xmote -> inode_go_sync ->
gfs2_log_flush).
