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...

CVE-2026-46067

CVE-2026-46067 affects the Linux kernel DAMON core. The issue arises because the code path in mm/damon/core validates the node-datas used by NODE-DATA() relies on damos_quota_goal->nid but does not validate its value, allowing an arbitrary nid to be supplied for node_memcg_{used,free}_bp. This...

CVE-2026-46067

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: validate damosquotagoal-nid for nodememcgused,freebp Users can set damosquotagoal-nid with arbitrary value for nodememcgused,freebp. But DAMON core is using those for NODE-DATA without a validation of the value. Th...

SUSE CVE-2026-45838

In the Linux kernel, the following vulnerability has been resolved: bpf: fix end-of-list detection in cgroupstoragegetnextkey listnextentry never returns NULL -- when the current element is the last entry it wraps to the list head via containerof. The subsequent NULL check is therefore dead code...

CVE-2026-45838

A flaw was found in the Linux kernel. Specifically, within the Berkeley Packet Filter BPF component, an error in the cgroupstoragegetnextkey function's end-of-list detection mechanism can cause the system to read from an invalid memory location. This incorrect handling may lead to internal map...
