CVE-2026-74262

A flaw was found in the Linux kernel's Kernel Connection Multiplexor KCM module. This vulnerability occurs due to a race condition when the KCM module replaces or restores lower TCP socket callbacks. If another central processing unit CPU observes an outdated callback state, it can lead to...

CVE-2026-68201 ALSA: timer: drain a slave's callback before its master detaches it

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: drain a slave's callback before its master detaches it sndtimercloselocked drains the closing instance's own in-flight callback IFLGCALLBACK before freeing it, but not its slaves'. When a master instance is closed,...

CVE-2026-68201

The CVE-2026-68201 issue affects the Linux kernel ALSA timer: when closing a master timer, a slave’s in-flight callback may run after detach, causing use-after-free. The fix drains slave callbacks before removing slave links, and stops pending/active callbacks on the slave side before freeing. Th...

CVE-2026-68198

The CVE-2026-68198 issue affects the Linux kernel’s ath6kl Wi‑Fi driver, specifically aggr_reset_state(). The non-synchronous timer deletion (timer_delete) can race with timer callbacks (aggr_timeout) that access aggr_conn fields, potentially freeing memory used by the callback, leading to a use‑...

CVE-2026-68178

CVE-2026-68178 concerns the Linux kernel NSM (Network Shared Memory) misc device. The root cause is that misc_open() installs file_operations with fops_get() which pins file_operations::owner, but NSM’s misc device left nsm_dev_fops.owner unset, allowing an open /dev/nsm descriptor to survive an ...
