CVE-2026-74372

CVE-2026-74372 concerns the Linux kernel RAID1 code path. In raid1_write_request(), every per-mirror iteration starts by incrementing rdev->nr_pending. If a REQ_ATOMIC write hits a badblock within the range, control jumps to err_handle without dropping the reference for the current mirror. The...

CVE-2026-74373

The CVE-2026-74373 entry documents a Linux kernel issue in md/raid1 and raid10 where bio accounting was incorrect for split md cloned bios. The mitigation implemented is to use md_cloned_bio() to detect md cloned bios and skip accounting accordingly, replacing reliance on r1bio_existed (raid1) or...

CVE-2026-74371

CVE-2026-74371 concerns a Linux kernel BPF issue where BPF_PROG_QUERY could cause an OOB write by unconditionally writing query.revision to userspace when a smaller bpf_attr buffer is provided. The fixes propagate the user-supplied attribute size (uattr_size) down to cgroup query handlers and ski...
