CVE-2026-46223

The CVE-2026-46223 issue concerns the Linux kernel cgroup subsystem: rmdir defers percpu_ref kill of CSS until the cgroup is depopulated. A chain of commits reworked rmdir behavior to ensure ->css_offline() does not run while tasks are still doing kernel work in the cgroup. The core problem wa...

CVE-2026-46154

CVE-2026-46154 affects the Linux kernel sched_ext functionality. Root cause: in cgroup setters, scx_group_set_{weight,idle,bandwidth}() cache the scx_root before acquiring scx_cgroup_ops_rwsem, enabling a window where the pointer can become stale if a scheduler is disabled and freed (via RCU) and...

CVE-2026-46121

The CVE-2026-46121 issue affects the Linux kernel DAMON sysfs interface (mm/damon/sysfs-schemes). A race between reads and writes of memcg_path and path can lead to a use-after-free when a user reads or writes the sysfs files while a buffer is being deallocated. The root cause is that user-direct...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the cgroup setter in schedext reading scxroot before acquiring a lock. This could lead to reusing...
