- Summary
- CVE-2025-68797 affecting package kernel for versions less than 6.6.121.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
char: applicom: fix NULL pointer dereference in ac_ioctl
Discovered by Atuin - Automated Vulnerability Discovery Engine.
In ac_ioctl, the validation of IndexCard and the check for a valid RamIO pointer are skipped when cmd is 6. However, the function unconditionally executes readb(apbs[IndexCard].RamIO + VERS) at the end.
If cmd is 6, IndexCard may reference a board that does not exist (where RamIO is NULL), leading to a NULL pointer dereference.
Fix this by skipping the readb access when cmd is 6, as this command is a global information query and does not target a specific board context.
