CVE-2026-23356

The CVE-2026-23356 issue affects the Linux kernel DRBD subsystem. A logic bug in drbd_al_begin_io_nonblock() could mis-handle a reference-counted extent when lc_get_cumulative() and lc_try_lock() timing collided, risking a crash or incorrect assumption that an activity log extent is active during...

CVE-2026-23330

Summary: CVE-2026-23330 affects the Linux kernel NFC/NCI subsystem. The issue arises in nci_close_device() where pending data exchanges may not be completed before closing, allowing a leaking unreferenced socket object (example: 0xff1100000f435000, size 2048) and associated references. This could...
