CVE-2026-92499

CVE-2026-92499 affects the Linux kernel ext4 filesystem. A corrupted directory entry with an invalid rec_len field can cause ext4_readdir() to resume from an invalid offset, resulting in an out-of-bounds read that KASAN reports as a use-after-free in __ext4_check_dir_entry(). The rescan path only...
