CVE-2026-80720

CVE-2026-80720 affects the Linux kernel iomap subsystem (file ioend.c). The root cause is that iomap_split_ioend can split block I/O requests (bios) that were already allocated from the shared iomap_ioend_bioset, creating a deadlock when that bioset becomes exhausted. The fix introduces a separat...
