CVE-2022-50103

CVE-2022-50103: In the Linux kernel, sched/cpuset handling with cgroup v2 can lead to a panic when cpus_allowed is empty, causing dl_cpu_busy() to crash due to an out-of-bounds percpu access. The fix uses the effective_cpus mask instead of cpus_allowed, for both v1 (where they’re the same) and v2...

CVE-2022-50103 sched, cpuset: Fix dl_cpu_busy() panic due to empty cs->cpus_allowed

In the Linux kernel, the following vulnerability has been resolved: sched, cpuset: Fix dlcpubusy panic due to empty cs-cpusallowed With cgroup v2, the cpuset's cpusallowed mask can be empty indicating that the cpuset will just use the effective CPUs of its parent. So cpusetcanattach can call...
