- Summary
- CVE-2023-52596 affecting package kernel 5.15.200.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
sysctl: Fix out of bounds access for empty sysctl registers
When registering tables to the sysctl subsystem there is a check to see if header is a permanently empty directory (used for mounts). This check evaluates the first element of the ctl_table. This results in an out of bounds evaluation when registering empty directories.
The function registersysctlmountpoint now passes a ctltable of size 1 instead of size 0. It now relies solely on the type to identify a permanently empty register.
Make sure that the ctl_table has at least one element before testing for permanent emptiness.
