安全等级: Critical
公告ID: KylinSec-SA-2023-2223
发布日期: 2023年8月12日
关联CVE: CVE-2023-38430 CVE-2023-4004 CVE-2023-38429 CVE-2023-38427
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)
