CVE-2026-68386

A flaw was found in the Linux kernel. A local attacker with BPF program capabilities could exploit a vulnerability in the BPF sockmap feature. This occurs when a BPF program increments the reference count of an unbound UDP socket, and the socket is subsequently bound. This sequence of events caus...

CVE-2026-68206

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-2026-68371

In the Linux kernel, the following vulnerability has been resolved: usb: musb: omap2430: Do not put borrowed ofnode in probe omap2430probe stores pdev-dev.ofnode in a local np variable. This is a borrowed pointer and the probe function does not take a reference to it. The success and error paths...

CVE-2026-68238

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Release VFCT ACPI table reference amdgpuacpivfctbios fetches the VFCT table with acpigettable but never releases it. acpigettable takes a reference on the table incrementing its validationcount and mapping it on the 0...

UBUNTU-CVE-2026-68205

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-2026-68371

The CVE concerns the Linux kernel USB MUSB OMAP2430 driver. In omap2430_probe(), pdev->dev.of_node is stored in a local np variable as a borrowed pointer and the code later calls of_node_put(np). This drops a reference owned by the platform device, potentially leaving pdev->dev.of_node with...

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...
