An update for kernel is now available for openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1727 Final 1.0 1.0 2023-10-13 Initial 2023-10-13 2023-10-13 openEuler SA Tool V1.0 2023-10-13 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP1. The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in the Linux kernel before 5.8.6. drivers/media/cec/core/cec-api.c leaks one byte of kernel memory on specific hardware to unprivileged users, because of directly assigning log_addrs with a hole in the struct.(CVE-2020-36766) An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.(CVE-2023-42753) An update for kernel is now available for openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
