UBUNTU-CVE-2026-74392

In the Linux kernel, the following vulnerability has been resolved: dm: limit target bio polling to one shot dmpollbio is the -pollbio callback for a stacked dm device. The caller only knows about the dm queue, so it may decide to do a spinning poll if it thinks a single queue is being polled...

CVE-2026-74375

In the Linux kernel, the following vulnerability has been resolved: md/raid1,raid10: fix deadlock in read error recovery path raid1d and raid10d may resubmit a split md cloned bio while handling a read error. In this case, resubmitting the bio can lead to a deadlock if the array is suspended befo...

CVE-2026-74392

Summary of CVE-2026-74392 (Linux kernel, device-mapper): The issue involves the dm_poll_bio() callback used by stacked dm devices. The caller only knows about the dm queue and could initiate spinning polls, passing flags unchanged to the mapped clone, which may cause blk_mq_poll() to spin on a ta...

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...
