kernel security update
安全等级: High
公告ID: KylinSec-SA-2023-2231
发布日期: 2023年8月18日
关联CVE: CVE-2023-4133 CVE-2023-4147 CVE-2023-3863 CVE-2023-3772
The Linux Kernel, the operating system core itself.
Security Fix(es):
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service.(CVE-2023-3772)
A use-after-free flaw was found in nfc_llcp_find_local in net/nfc/llcp_core.c in NFC in the Linux kernel. This flaw allows a local user with special privileges to impact a kernel information leak issue.(CVE-2023-3863)
A use-after-free vulnerability was found in the cxgb4 driver in the Linux kernel. The bug occurs when the cxgb4 device is detaching due to a possible rearming of the flower_stats_timer from the work queue. This flaw allows a local user to crash the system, causing a denial of service condition.(CVE-2023-4133)
A use-after-free flaw was found in the Linux kernel’s Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.(CVE-2023-4147)
