CVE-2026-53180

A flaw was found in the Linux kernel's timer migration handling. An incorrect assumption in the tmigrhandleremotecpu function regarding local softirq path handling of CPU timers can lead to a livelock. This occurs when a timer expires after the local timer wheel advances but before remote handlin...

CVE-2026-53193

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. This vulnerability occurs when a timer object is freed while timer instances are still associated with it, particularly when userspace-driven timers are involved. A local user can exploit this by...

SUSE CVE-2026-53180

In the Linux kernel, the following vulnerability has been resolved: timers/migration: Fix livelock in tmigrhandleremoteup tmigrhandleremotecpu skips timerexpireremote when cpu == smpprocessorid, assuming the local softirq path already handled this CPU's timers. This assumption is wrong because...

SUSE CVE-2026-53192

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: Fix UAF at sndtimeruserparams At releasing a timer object, e.g. when a userspace timer CONFIGSNDUTIMER gets closed and sndtimerfree is called, it tries to detach the timer instances and release the resources. However...

SUSE CVE-2026-53193

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: Forcibly close timer instances at closing When sndtimer object is freed via sndtimerfree and still pending sndtimerinstance objects are assigned to the timer object, it tries to unlink all instances and just set NULL...

SUSE CVE-2026-53260

In the Linux kernel, the following vulnerability has been resolved: tcp: Add preemptdisable,enablenested in reqskqueuehashreq. syzbot reported a weird reqsk-rskrefcnt underflow in inetcskreqskqueuedrop.

CVE-2026-53192

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A race condition can occur during the release of a timer object, specifically when the SNDRVTIMERIOCTLPARAMS ioctl is called concurrently. This can lead to a use-after-free vulnerability, potentially...
