CVE-2026-80691 scsi: target: iblock: Fix wrong PR ops NULL check for PREEMPT/RELEASE

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iblock: Fix wrong PR ops NULL check for PREEMPT/RELEASE In the iblockexecuteprout function, PROPREEMPT, PROPREEMPTANDABORT, and PRORELEASE all perform callback capability checks through ops-prclear. The error check...

CVE-2026-80691

CVE-2026-80691 is a NULL pointer dereference in the Linux kernel SCSI target iblock subsystem . In iblock_execute_pr_out(), the PRO_PREEMPT , PRO_PREEMPT_AND_ABORT , and PRO_RELEASE operations perform capability checks through ops->pr_clear; the flawed check allows unimplemented hooks to pass,...

CVE-2026-80690

CVE-2026-80690 affects the Linux kernel UFS (Universal Flash Storage) SCSI driver. The root cause is that the hba->rpmbs list is not initialized in ufshcd_alloc_host(), leading to a NULL pointer dereference in the device teardown path when ufs_rpmb_probe() fails. The fix is a list initializati...
