kernel: mm/slub: actually fix freelist pointer vs redzoning

In the Linux kernel, the following vulnerability has been resolved: mm/slub: actually fix freelist pointer vs redzoning It turns out that SLUB redzoning "slubdebug=Z" checks from s-objectsize rather than from s-inuse which is normally bumped to make room for the freelist pointer, so a cache creat...

PT-2024-11230 · Linux +3 · Linux Kernel +3

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to the SLUB redzoning feature in the Linux kernel, which checks for corruption from s-object size instead of s-inuse. This can cause the freelist pointer to be...
