In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix bo-pin leaking in amdgpubocreatereserved amdgpubocreatereserved only allocates a new BO when boptr struct amdgpubo boptr as input parameter is NULL, it simply skips creation when boptr is non-NULL. But it...

CVE-2026-68226 media: cx23885: add ioremap return check and cleanup

In the Linux kernel, the following vulnerability has been resolved: media: cx23885: add ioremap return check and cleanup Add a check for the return value of pciioremapbar in cx23885devsetup. If ioremap for BAR0 fails, release the already allocated PCI memory region, decrement the device count, an...

CVE-2026-68206 media: v4l2-ctrls: validate HEVC active reference counts

In the Linux kernel, the following vulnerability has been resolved: media: v4l2-ctrls: validate HEVC active reference counts HEVC slice parameters are shared stateless V4L2 controls, but the common validation path does not verify the active L0/L1 reference counts before driver-specific code...

CVE-2026-68205 media: v4l2-fwnode: Fix subdev owner overwritten in v4l2_async_register_subdev_sensor()

In the Linux kernel, the following vulnerability has been resolved: media: v4l2-fwnode: Fix subdev owner overwritten in v4l2asyncregistersubdevsensor The v4l2 helper v4l2asyncregistersubdevsensor calls v4l2asyncregistersubdev, which is a macro that expands to v4l2asyncregistersubdevsd,THISMODULE...

CVE-2026-68177 tracing: Delay module ref count for "enable_event" trigger

In the Linux kernel, the following vulnerability has been resolved: tracing: Delay module ref count for "enableevent" trigger Triggers are now delayed from freeing, but can still be triggered until after the RCU grace period has ended. The freeing of the enableevent data is put into the...

CVE-2026-68177

The CVE-2026-68177 entry describes a Linux kernel tracing vulnerability in which delaying the release of a module that contains an active enable/disable event leads to use-after-free if the module is removed while still referenced by an event. The underlying issue is that the module refcount is r...

CVE-2026-68174

The vulnerability CVE-2026-68174 affects the Linux kernel tracing subsystem. In struct trace_event_call, the module pointer and the refcnt atomic share a union, so for dynamic events (kprobe, uprobe, fprobe, eprobe, wprobe) the refcnt may be non-zero and cause call->module to appear as a small...

CVE-2026-68138

The CVE-2026-68138 issue concerns a race in the Linux kernel networking scheduler (net/sched) where qdisc_rtab_list and a non-atomic refcnt are mutated without proper locking. The historical RTNL mutex was supposed to serialize rate-table lookups, inserts, and frees, but CLS_FLOWER/TCF_PROTO_OPS_...

CVE-2026-68122

CVE-2026-68122: Linux kernel ovpn code has a race in TCP error paths where ovpn_peer_hold() refs can be leaked if schedule_work() is already pending. The fix is to check schedule_work() return value on both RX/TX error paths and drop the extra reference with ovpn_peer_put() when the work is alrea...

CVE-2026-68098

CVE-2026-68098 affects ksmbd in the Linux kernel. The root cause is in set_ntacl_dacl(), which can stop copying ACEs when DACL size accounting overflows. As a result, the dedup walk may inspect a tail beyond the copied ACEs, potentially enabling an out-of-bounds read with possible denial of servi...

CVE-2026-68098

In the Linux kernel, the following vulnerability has been resolved: ksmbd: bound DACL dedup walk to copied ACEs setntacldacl can stop copying ACEs before consuming the full input DACL when size accounting overflows. When that happens, numaces reflects only the ACEs that were actually copied into...

CVE-2026-68098 ksmbd: bound DACL dedup walk to copied ACEs

In the Linux kernel, the following vulnerability has been resolved: ksmbd: bound DACL dedup walk to copied ACEs setntacldacl can stop copying ACEs before consuming the full input DACL when size accounting overflows. When that happens, numaces reflects only the ACEs that were actually copied into...

kernel: dm log: fix out-of-bounds write due to region_count overflow

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...
