CVE-2026-74375

In the Linux kernel, md/raid1 and raid10 components were hardened to prevent a deadlock during read-error recovery. Specifically, when handling a read error, raid1d/raid10d could resubmit a split md cloned bio while an array is suspended, and attempt to acquire a second active_io reference via pe...

In the Linux kernel, the following vulnerability has been resolved: md/raid1,raid10: fix error-path detection with mdclonedbio Detect the error path using mdclonedbio instead of relying on r1bio in raid1 or r10bio-readslot in raid10, which may be NULL or -1 after splitting and resubmitting a fail...

CVE-2026-74374 md/raid1,raid10: fix error-path detection with md_cloned_bio()

In the Linux kernel, the following vulnerability has been resolved: md/raid1,raid10: fix error-path detection with mdclonedbio Detect the error path using mdclonedbio instead of relying on r1bio in raid1 or r10bio-readslot in raid10, which may be NULL or -1 after splitting and resubmitting a fail...

CVE-2026-74374

CVE-2026-74374 affects the Linux kernel’s md/raid1 and md/raid10 code paths. The fix replaces error-path detection that relied on r1_bio or raid10’s read_slot with md_cloned_bio(), addressing cases where the error path is NULL or -1 after bio splitting/resubmission. The consequence previously cou...

CVE-2026-74354

CVE-2026-74354 : In the Linux kernel, a vulnerability in the BPF zap_pages path is resolved by changing how mmap_lock is taken for zap_vma_range(). The root cause is that zap_vma_range() requires the owning mm’s mmap_lock to be held, and taking mmap_read_lock under arena->lock could AB-BA agai...
