AI-suggested
An official fix is available and should be applied by upgrading to patched Linux kernel versions. The affected versions are prior to 5.15.0-1103.110~20.04.1, 5.15.0-1110.119~20.04.1, 5.15.0-1114.123~20.04.1, 5.15.0-1103.112~20.04.1, and 5.15.0-173.183~20.04.1. Users should update their kernels to versions including these patches to prevent kernel panics related to this vulnerability.
Description
A vulnerability in the Linux kernel's f2fs filesystem code was fixed by correcting the return value handling of the f2fs_recover_fsync_data() function. Improper error handling during mounting with read-only options like ro,norecovery or ro,disable_roll_forward could cause a kernel panic. This issue affects certain Linux kernel versions prior to specific patched releases. The vulnerability has been addressed with an official fix.
