CVE-2026-93140

CVE-2026-93140 affects the Linux kernel's UDF filesystem . When an I/O error occurs while writing the Logical Volume Integrity Descriptor (LVID) buffer, the block layer clears the BH_Uptodate flag, even though the in-memory data remains valid. Subsequent calls to udf_open_lvid() or udf_sync_fs() ...

CVE-2026-93055

CVE-2026-93055 affects the Linux kernel's UDF filesystem implementation. The vulnerability is an out-of-bounds (OOB) read in the handling of UDF symlinks: udf_symlink_filler() can pass a partial pathComponent header to udf_pc_to_char(), which then reads beyond the available input. The fix validat...
