CVE-2022-50082

CVE-2022-50082 affects the Linux kernel ext4 subsystem. The issue arises in ext4_iomap_begin due to a race between bmap and write, which can trigger a WARN_ON_ONCE path during file writes, evidenced by a kernel warning trace through iomap_apply → iomap_bmap → ext4_bmap → bmap. The consequence is ...
