Amazon Linux 2 Security Advisory: ALASKERNEL-5.10-2024-049
Advisory Release Date: 2024-02-01 20:10 Pacific
Advisory Updated Date: 2024-02-01 20:10 Pacific
A Linux Kernel flaw found in memory management. If allocation failure happens in pagefault_out_of_memory with VM_FAULT_OOM, then it can lead to memory overflow when many tasks trigger this. An issue may cause multi-tenant denial of service (memory overflow). It was reported that a malicious workload may be allowed to OOM-kill random other workloads on the same node. (CVE-2023-0047)
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. (CVE-2023-1252)
