Red Hat Security Advisory 2024-4447-03 - An update for kernel is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions, and Red Hat Enterprise Linux 8.6 Telecommunications Update Service. Issues addressed include code execution, null pointer, and use-after-free vulnerabilities.
Red Hat Security Advisory 2023-7077-01 - An update for kernel is now available for Red Hat Enterprise Linux 8. Issues addressed include buffer overflow, denial of service, double free, information leakage, memory leak, null pointer, out of bounds access, out of bounds write, and use-after-free vulnerabilities.
A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet, the kernel could be affected.
The kernel tree of CentOS Stream 9 suffers from multiple use-after-free conditions that were already patched in upstream stable trees.
