CVE-2026-90121

CVE-2026-90121 affects the Linux kernel GICv5 interrupt controller driver (irqchip/gic-v5). During IRS (Interrupt Routing Structure) affinity setup, an IRS pointer and IAFFID state are published in per-CPU data before the remaining initialization can fail. On the error path and normal teardown, t...

In the Linux kernel, the following vulnerability has been resolved: ALSA: mtpav: shut down output timer before card teardown sndmtpavoutputtimer rearms chip-timer while holding chip-spinlock and accesses the card-private mtpav state. sndmtpavfree currently takes the same lock and calls timerdelet...

CVE-2026-90117 ntfs: validate usa_ofs before preserving the update sequence number

In the Linux kernel, the following vulnerability has been resolved: ntfs: validate usaofs before preserving the update sequence number When ntfsmftrecordalloc reuses a free mft record it reads the old update sequence number straight from the on-disk record: usn = le16 u8 m + le16tocpum-usaofs; He...

CVE-2026-90117

CVE-2026-90117 affects the Linux kernel's NTFS filesystem driver . In ntfs_mft_record_alloc(), when reusing a free MFT record, the usa_ofs field is read directly from a raw $MFT page-cache folio without validation. Because MST fixup and record checking operate on private copies, usa_ofs remains a...

CVE-2026-90116

CVE-2026-90116 affects the Linux kernel's ALSA mtpav driver (MTP Audio). The vulnerability is a race condition during card teardown: the timer callback snd_mtpav_output_timer() can execute on another CPU after snd_mtpav_free() releases the spinlock, accessing card-private mtpav state that is bein...

CVE-2026-90113

CVE-2026-90113 is a slab-use-after-free vulnerability in the Linux kernel's netdevsim (network device simulator) driver. The root cause is that nsim_queue_start() failed to update the queue-to-NAPI mapping via netif_queue_set_napi() when a new receive queue was swapped in during a queue reset. Th...

CVE-2026-90111

CVE-2026-90111 is a slab use-after-free in the Linux kernel's IPv6 multicast routing (ip6mr) subsystem. When an ingress multicast packet misses the MFC lookup, the skb is queued on the unresolved queue, escaping the receive-side RCU grace period. If the underlying route is subsequently deleted an...
