Vulnerability from github – Published: 2024-01-18 18:30 – Updated: 2024-06-27 12:30
VLAI?
Details

A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the dst array. On each iteration, 8 bytes are written, but dst is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element, possibly leading to an out-of-bounds write. This flaw allows a local user to cause a denial of service or potentially escalate their privileges on the system.

Severity ?
7.8 (High)
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
