An update for kernel is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1496 Final 1.0 1.0 2023-08-12 Initial 2023-08-12 2023-08-12 openEuler SA Tool V1.0 2023-08-12 kernel security update An update for kernel is now available for openEuler-22.03-LTS. The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in the Linux kernel before 6.3.8. fs/smb/server/smb2pdu.c in ksmbd has an integer underflow and out-of-bounds read in deassemble_neg_contexts.(CVE-2023-38427) An issue was discovered in the Linux kernel before 6.3.4. fs/ksmbd/connection.c in ksmbd has an off-by-one error in memory allocation (because of ksmbd_smb2_check_message) that may lead to out-of-bounds access.(CVE-2023-38429) An issue was discovered in the Linux kernel before 6.3.9. ksmbd does not validate the SMB request protocol ID, leading to an out-of-bounds read.(CVE-2023-38430) A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.(CVE-2023-4004) An update for kernel is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of critical. 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.
