UBUNTU-CVE-2026-23313

In the Linux kernel, the following vulnerability has been resolved: i40e: Fix preempt count leak in napi poll tracepoint Using getcpu in the tracepoint assignment causes an obvious preempt count leak because nothing invokes putcpu to undo it: softirq: huh, entered softirq 3 NETRX with preemptcoun...

CVE-2026-23380

CVE-2026-23380 (Linux kernel) describes a local vulnerability in tracing buffers memory management. When a process forks, the child’s VMAs copy the parent’s without incrementing user_mapped, so exiting both processes may cause tracing_buffers_mmap_close() to run twice; on the second call user_map...

CVE-2026-23356

In the Linux kernel, the following vulnerability has been resolved: drbd: fix "LOGIC BUG" in drbdalbeginiononblock Even though we check that we "should" be able to do lcgetcumulative while holding the device-allock spinlock, it may still fail, if some other code path decided to do lctrylock with...

CVE-2026-23356

The CVE-2026-23356 issue affects the Linux kernel DRBD subsystem. A logic bug in drbd_al_begin_io_nonblock() could mis-handle a reference-counted extent when lc_get_cumulative() and lc_try_lock() timing collided, risking a crash or incorrect assumption that an activity log extent is active during...

CVE-2026-23313

CVE-2026-23313 : In the Linux kernel, a preempt-count leak was fixed in the i40e driver by replacing get_cpu() with smp_processor_id() in the napi poll tracepoint assignment. The leak occurred because put_cpu() was not invoked to undo the cpu reference, as illustrated by preempt_count traces. The...
