Overview
CVE-2026-98224 is a known-severity vulnerability. It was published on October 6, 2026.
Technical description
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.

How can CyberStrike help with CVE-2026-98224?
CyberStrike is an open-source, AI-augmented pentesting engine.
