Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.0.0-rc4

Description The Linux kernel contains a flaw within the f2fs file system related to sanity checks on summary information. This issue can lead to a use-after-free condition, specifically triggered by corrupted SSA tables where the ofs in node value exceeds the ADDRS PER PAGE limit, resulting in out-of-range access. The root cause lies in the recover data function, impacting recovery and garbage collection processes.
