- Summary
- CVE-2024-50127 affecting package kernel for versions less than 6.6.64.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: sched: fix use-after-free in taprio_change()
In 'tapriochange()', 'admin' pointer may become dangling due to sched switch / removal caused by 'advancesched()', and critical section protected by 'q->currententrylock' is too small to prevent from such a scenario (which causes use-after-free detected by KASAN). Fix this by prefer 'rcureplacepointer()' over 'rcuassignpointer()' to update 'admin' immediately before an attempt to schedule freeing.
