CVE-2026-89517

CVE-2026-89517 affects the Linux kernel's sched_ext (sched_ext) subsystem under core scheduling . Since commit 4c95380701f5, sched_ext's dispatch runs inside pick_next_task() and can drop the core-wide rq lock. When selections on the same core interleave through this dropped lock, they corrupt ea...

CVE-2026-89511

CVE-2026-89511 is a NULL pointer dereference in the qede driver (QLogic 10GbE Ethernet) of the Linux kernel , leading to a kernel panic and Denial of Service (CVSS 3.1: 7.5 HIGH , AV:N/AC:L/PR:N). The root cause is a dropped assignment of tpa_info->buffer.data in qede_tpa_start(), introduced b...
