Name of the Vulnerable Software and Affected Versions: Linux kernel versions through 5.12.7 Description: The issue is related to a buffer overflow in the kernel/bpf/verifier.c component of the Linux kernel, allowing an attacker to perform out-of-bounds reads and writes in kernel memory. This can...

Updated kernel-linus packages fix security vulnerabilities

This kernel-linus update is based on upstream 5.10.37 and fixes at least the following security issues: It was discovered that the iouring implementation of the Linux kernel did not properly enforce the MAXRWCOUNT limit in some situations. A local attacker could use this to cause a denial of...

SUSE-SU-2021:1605-1 Security update for the Linux Kernel

The SUSE Linux Enterprise 12 SP5 RT kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2020-36312: Fixed an issue within virt/kvm/kvmmain.c that had a kvmiobusunregisterdev memory leak upon a kmalloc failure bnc1184509. - CVE-2021-29650: Fix...

kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads leading to disclosure of stack content via side-channel attacks aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel.
