AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSET_CMD_ADD and IPSET_CMD_SWAP can lead to a kernel panic due to the invocation of `__ip_set_put` on a wrong `set`. This issue may allow a local user to crash the system.

CVE-2023-42756 is a race condition vulnerability identified in the Netfilter subsystem of the Linux kernel, specifically affecting Red Hat Enterprise Linux 9. The flaw occurs due to improper synchronization between two commands: IPSET_CMD_ADD and IPSET_CMD_SWAP. These commands manipulate IP sets used for packet filtering and firewall rules. The race condition can lead to the kernel invoking the function __ip_set_put on an incorrect 'set' object, which results in a kernel panic. This kernel panic causes the system to crash, leading to a denial-of-service condition. The vulnerability requires local user access with high privileges (PR:H) and does not require user interaction (UI:N). The impact is limited to availability (A:H), with no direct confidentiality or integrity compromise. The CVSS vector (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H) indicates that the attack surface is local, with low attack complexity, but requiring high privileges. No known exploits have been reported in the wild, and no patches were linked in the provided data, though Red Hat typically issues updates for such vulnerabilities. The vulnerability highlights the risks inherent in concurrent execution and resource sharing in kernel subsystems, emphasizing the need for proper synchronization mechanisms to prevent race conditions.
