hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I96YK9 CVE: NA ----------------------------- It's fine that the associated msc is not found when the CPU comes online. For example, the device platform does not support L3 cache and there is no any L3 cache msc indeed.

[PATCH OLK-5.10] arm64/mpam: Fix use-after-free when deleting resource groups
by Zeng Heng 12 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I97KAV -------------------------------- Refer to the below commit: commit b8511ccc75c0 ("x86/resctrl: Fix use-after-free when deleting resource groups") Before removing rdtgroup, we need to refer to waitcount counter, otherwise when unmounting the resctrl file system or deleting ctrl_mon groups, and there were a waiter on resctrl system, then a use-after-free issue would occurs. Fix that by removing rdtgroup after checking the waitcount.
