runc: opencontainers/selinux: container escape and denial of service due to arbitrary write gadgets and procfs write redirects

A flaw was found in runc. This attack is a more sophisticated variant of CVE-2019-16884, which was a flaw that allowed an attacker to trick runc into writing the LSM process labels for a container process into a dummy tmpfs file and thus not apply the correct LSM labels to the container process...

kernel: Linux kernel: Use-after-free in proc_readdir_de() can lead to privilege escalation or denial of service.

A flaw was found in the Linux kernel. This use-after-free UAF vulnerability occurs in the procreaddirde function within the /proc filesystem. A local attacker with low privileges can exploit this by concurrently traversing specific directories while network devices are unregistered. This can lead...
