CVE-2024-1085

Use-after-free in Linux kernel's netfilter: nf_tables component

Published Jan 31, 2024 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
Description
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

The nft_setelem_catchall_deactivate() function checks whether the catch-all set element is active in the current generation instead of the next generation before freeing it, but only flags it inactive in the next generation, making it possible to free the element multiple times, leading to a double free vulnerability.

We recommend upgrading past commit b1db244ffd041a49ecc9618e8feb6b5c1afcdaa7.
