CVE-2026-93229

The Linux kernel is affected by a vulnerability in the nfsd component. Specifically, the hand-rolled seqcount-like protocol in nfsd_nl_rpc_status_get_dumpit() lacks a read memory barrier (smp_rmb) before its second counter check. On weakly-ordered architectures such as ARM and POWER , the CPU may...

CVE-2026-93222

The Linux kernel contains a vulnerability where the send_signal_locked() function rewrites sender IDs for the target namespace. Because group sends reuse the same siginfo structure, one recipient can inadvertently affect the next. The issue is resolved by copying the siginfo before modification. ...

CVE-2026-93221

The Linux kernel is vulnerable to a race condition in the nfsd component due to a lack of serialization when accessing boolean fields in nfsd_net. Specifically, the nfsd4_end_grace() function uses a plain boolean for grace_ended, allowing concurrent paths—such as the laundromat path and the RECLA...

CVE-2026-93218

The Linux kernel contains a vulnerability in the mm/huge_memory component related to how it handles device-private Page Middle Directories (PMDs). A race condition occurs when an HMM-based GPU driver interacts with madvise(MADV_FREE). Specifically, migrate_vma_pages() can flip a PMD to a device-p...

CVE-2026-93208

The Linux kernel contains a race condition in KASAN involving cache shrinking and CPU hotplug . Specifically, kmem_cache_shrink() fails to hold the cpus_read_lock(), allowing a race where objects are moved to a CPU's shrink_qlist just before that CPU goes offline. Because the offline CPU's list i...
