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 ublk: wait on ublk_dev_ready() instead of ub->completion
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...

CVE-2026-68169
The CVE-2026-68169 entry documents a race in Linux kernel mptcp_pm_userspace_get_local_id() where an address entry is looked up under a spinlock but its id is read after the lock is released, allowing a concurrent delete to free the entry and cause a use-after-free. Concrete details show the issu...
