- Summary
- mm/vma: correctly unaccount on mmap_prepare() failure
- Details
-
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.
