CVE-2026-68174 tracing: Fix union collision of module and refcnt for dynamic events
In the Linux kernel, the following vulnerability has been resolved: tracing: Fix union collision of module and refcnt for dynamic events In 'struct traceeventcall', the 'module' pointer and the 'refcnt' atomic variable share the same memory space in a union. For dynamic events, the union member i...

EUVD-2026-55274
In the Linux kernel, the following vulnerability has been resolved: ublk: wait on ublkdevready instead of ub-completion ub-completion is only re-armed by a successful STARTUSERRECOVERY. If the ublk server sends ENDUSERRECOVERY without one - e.g. its START failed with -EBUSY and the error was...
CVE-2026-68173
CVE-2026-68173 affects the Linux kernel ublk subsystem. The root cause is that ub->completion is an edge-triggered latch used as a proxy for the readiness condition; when a server sends END_USER_RECOVERY without a preceding START_USER_RECOVERY, the wait can be satisfied by a stale completion, ...

CVE-2026-68172
CVE-2026-68172 affects the arm64 Linux kernel where huge_ptep_get may mis-handle unaligned addresses across contpmd/contpte hugetlb foliοs. The arm64 helper may misclassify the target as CONT_PTES instead of CONT_PMDS, potentially causing excess A/D state handling, dereferencing a garbage ptep, o...
