How to fix?

There is no fixed version for Centos:10 perf.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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

mm/vma: correctly unaccount on mmap_prepare() failure

__mmap_setup() accounts memory for relevant mappings via:

security_vm_enough_memory_mm() -> __vm_enough_memory() -> vm_acct_memory()

If __mmap_setup() fails, this indicates that this accounting did not take place, and thus it's appropriate for __mmap_region() to jump to abort_munmap.

However if call_mmap_prepare() fails, it also jumps there and any accounted memory is not correctly unaccounted.

Fix this by handling each error separately.
