Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains an issue related to off-by-one errors in fast-commit block filling within the ext4 filesystem. These errors stem from constraints on how fast-commit blocks are filled with TLV (Type-Length-Value) entries. Specifically, TLVs must start at least 10 bytes before the end of the block and end at least 1 byte before the end of the block. Old kernels will be unable to replay fast-commit journals created by kernels with the fix.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
