CVE-2026-89552

This Linux kernel vulnerability affects param_set_charp() in the kernel's params subsystem. The root cause is that the previous parameter value is freed before the replacement allocation succeeds; if kmalloc_parameter() fails, the parameter is left as NULL , leading to a kernel NULL pointer deref...

CVE-2026-89544

CVE-2026-89544 affects the Linux kernel's SUNRPC subsystem, specifically the gssx_dec_option_array() XDR option-array decoder. Four coupled defects in its error paths introduce a NULL dereference (when oa->count is set before oa->data allocation fails), a refcount leak on cr_group_info (rel...

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...
