CVE-2026-90168

CVE-2026-90168 affects the ksmbd SMB server component of the Linux kernel . The root cause is a lifetime mismatch: deferred CHANGE_NOTIFY work retains an async message ID after the original request work is released. Because a durable handle can outlive its connection, connection teardown can dest...

CVE-2026-80841

CVE-2026-80841 is a use-after-free in the Linux kernel's AF_PACKET TX_RING subsystem. AF_PACKET TX_RING skbs hold a raw pointer to their ring frame; while page references preserve page-backed ring blocks after the ring vector is freed, they do not preserve a vmalloc mapping. This means a late skb...

CVE-2026-80753

In the Linux kernel, the following vulnerability has been resolved: ovpn: run deferred work on a module-owned workqueue ovpn queues several work items whose callbacks execute module text. These works currently run on the global system workqueues, so module exit has no driver-owned drain point tha...

CVE-2026-80753

CVE-2026-80753 affects the Linux kernel's ovpn module . Work items whose callbacks execute module text ran on the global system workqueues, meaning module exit had no driver-owned drain point to guarantee callbacks had returned before the module text could be freed. Specifically, a worker could d...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: Fixed the error code in iwlopmodedvmstart The error code should be preserved if iwlsetupdeferredwork fails. The current code returns ERRPTR0 which is NULL at this point. I believe that the missing error code could...

SUSE CVE-2026-63919

In the Linux kernel, the following vulnerability has been resolved: xfrm: input: hold netns during deferred transport reinjection Transport-mode reinjection stores a struct net pointer in skb-cb and uses it later from xfrmtransreinject. That pointer must stay valid until the deferred callback run...

CVE-2026-63919

The CVE-2026-63919 entry concerns the Linux kernel's xfrm input path and deferred transport reinjection. The vulnerability stems from storing a struct net pointer in skb->cb and later using it in xfrm_trans_reinject() without ensuring the netns lifetime, risking dereferencing a torn-down names...

PT-2026-61236

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the xfrm input component where the network namespace netns is not properly held during deferred transport reinjection. The process stores a struct net pointer in skb-c...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: schedext: A potential deadlock has been fixed in deferredirqworkfn. For PREEMPTRT=y kernels, deferredirqworkfn is executed in the per-cpu irqwork/ task context, and not in disable-irq. If the rq returned by containerof is the...

CVE-2026-45855

The CVE-2026-45855 issue affects the Linux kernel’s libata-scsi component, where NCQ command traffic could starve non-NCQ commands in multi-queue hosts. Root cause: mixing NCQ and non-NCQ can delay non-NCQ execution when NCQ is in-flight. The fix implements forward progress for non-NCQ commands b...
