Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.61
Description:
A kernel-infoleak issue was discovered in the Linux kernel, specifically in the xfrm algorithm dumping functionality. The issue was found during fuzz testing and is related to the copying of xfrm algorithms, where some random data of the structure fields can end up in userspace. Padding in structures may be filled with random, possibly sensitive data, and should never be given directly to user-space. The issue was discovered by the Linux Verification Center with Syzkaller.
Recommendations:
For Linux kernel versions prior to 6.6.61, update to version 6.6.61 or later to resolve the issue. As a temporary workaround, consider restricting access to the xfrm algorithm dumping functionality until a patch is available.
