The bug occurs when the regions array is indexed before its size (nregions) is set, causing a UBSAN array-index-out-of-bounds in drivers/mtd/devices/mtd_intel_dg.c:750:15. The issue is triggered by accessing regions before nregions is e...

CVE-2026-53167

CVE-2026-53167 affects the Linux kernel’s FUSE path: FUSE_NOTIFY_RETRIEVE must be limited to uptodate folios since !uptodate folios may contain uninitialized data. The vulnerability is scoped to systems without automatic page-alloc zero init (CONFIG_INIT_ON_ALLOC_DEFAULT_ON or init_on_alloc=1). E...

CVE-2026-53180

CVE-2026-53180 involves a Linux kernel timers/migration livelock. The issue arises when tmigr_handle_remote_cpu() skips timer_expire_remote() if cpu == smp_processor_id(), under the incorrect assumption that the local softirq path already handled this CPU’s timers. Jiffies can advance after local...

CVE-2026-53183

CVE-2026-53183 affects the Linux kernel MPTCP implementation. The issue allows the TCP subflow receive window to shrink independently of the netns, which can inflate the MPTCP receive window and cause incoming data to exceed the receiver’s rcvbuf, potentially leading to DoS or a system becoming u...

CVE-2026-53209

The CVE-2026-53209 issue affects the Linux kernel Bluetooth subsystem (hci_sync).

CVE-2022-50305

CVE-2022-50305 is a Linux kernel ASoC issue: sof_es8336_remove() could cause use-after-free because cancel_delayed_work() may not wait for the work function to finish. The fix uses cancel_delayed_work_sync() to ensure the work is cancelled, not running, and cannot be re-scheduled. Affected compon...

CVE-2022-50430

CVE-2022-50430 affects the Linux kernel mmc vub300 driver. The fix prevents calling blocking operations when the current task is not TASK_RUNNING by ensuring vub300_enable_sdio_irq() uses proper mutex usage and marks the current task as TASK_RUNNING in a sleepable context. This reduces a potentia...

CVE-2022-50437

CVE-2022-50437 - Linux kernel (drm/msm/hdmi) : A memory corruption issue was fixed by adding a missing sanity check on the bridge counter to prevent writing beyond the fixed-sized bridge array when there are more than eight bridges.
