CVE-2026-90278

CVE-2026-90278 is a use-after-free vulnerability in the Linux kernel's md (multiple device) subsystem , specifically in the bitmap teardown path of __md_stop(). The bug occurred because the bitmap was destroyed before mddev_detach() was called, causing the detach path to skip bitmap_ops->wait_...

CVE-2026-90275

CVE-2026-90275 is a Linux kernel bug in the md/raid1 (Software RAID mirror) driver. In raid1_takeover(), the code sets conf->array_frozen = 1 on the newly-allocated r1conf structure, but nothing subsequently clears it. This became impactful after commit b39f35ebe86d ("md: don't quiesce in mdde...
