Threats tagged 'ghsa-w7vv-57v2-cqgf'

A high-severity vulnerability in the Linux kernel's ext4 filesystem code involving a potential buffer over-read in the parse_apply_sb_mount_options() function has been resolved. The issue arises because the s_mount_opts string in the ext4 superblock was assumed to be NUL terminated by tune2fs, but this assumption was hardened to treat s_mount_opts as a potential non-string to avoid over-read. This vulnerability could impact confidentiality, integrity, and availability of the system. No known exploits are reported in the wild. No specific affected versions are provided. Patch status is not confirmed in the provided data.
