Important: kernel

Issue Overview: A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose handler could happen if removing device that is not common to remove video card physically without power-off, but same happens if unbind the driver. CVE-2020-27820 A flaw use-after-free in...

kernel: eBPF: insufficient stack type checks in dynptr

An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAPBPF privileges to escalate privileges and...
