Amazon Linux 2 Security Advisory: ALASKERNEL-5.15-2024-034
Advisory Release Date: 2024-01-19 02:20 Pacific
Advisory Updated Date: 2024-01-19 02:20 Pacific
An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information. (CVE-2023-6606)
A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with CAP_NET_ADMIN capability to escalate their privileges on the system. (CVE-2024-0193)
