OESA-2022-1517 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: A double free bug in packetsetring in net/packet/afpacket.c can be exploited by a local user through crafted syscalls to escalate privileges or deny service. We recommend upgrading kernel past the effected versions or rebuilding...

The vulnerability of the `package_set_ring` function in the `net/packet/af_packet.c` component of the Linux kernel allows a hacker to increase their privileges within the system or cause a service failure.

The vulnerability of the packagesetring function in the net/packet/afpacket.c component of the Linux kernel is related to the reallocation of memory. Exploiting this vulnerability could allow a remote attacker to increase their privileges within the system or cause service failures...

Important: kernel

Issue Overview: A flaw was found in the Linux kernel, where a BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack. This issue occurs when the protection mechanism neglects the possibility of uninitialized memory locations on the BPF...
