The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2025:15472 advisory. kernel: bpf: Don't use tnumrange on array range checking for poke descriptors CVE-2022-49985 kernel: posix-cpu-timers: fix race between...

kernel: posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()

A race condition was found in the Linux kernel’s POSIX CPU timer handling, where handleposixcputimers may run concurrently with posixcputimerdel on an exiting task which could result in use-after-free scenarios. An attacker with local user access could use this flaw to crash or escalate their...

The vulnerability of the `handle_posix_cpu_timers` function in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the handleposixcputimers function in the Linux operating system’s kernel is related to state management errors. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

VulnCheck KEV: CVE-2025-38352

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: fix race between handleposixcputimers and posixcputimerdel If an exiting non-autoreaping task has already passed exitnotify and calls handleposixcputimers from IRQ, it can be reaped by its parent or debugger rig...

ASB-A-425282960

In runposixcputimers of posix-cpu-timers.c, there is a possible way to trigger a use-after-free on a sigqueue object due to memory corruption. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...
