Description

CVE-2024-50127 affecting package kernel for versions less than 6.6.64.2-1

In the Linux kernel, the following vulnerability has been resolved:

net: sched: fix use-after-free in taprio_change()

In 'taprio_change()', 'admin' pointer may become dangling due to sched

switch / removal caused by 'advance_sched()', and critical section

protected by 'q->current_entry_lock' is too small to prevent from such

a scenario (which causes use-after-free detected by KASAN). Fix this

by prefer 'rcu_replace_pointer()' over 'rcu_assign_pointer()' to update

'admin' immediately before an attempt to schedule freeing.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
