CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-6111 – Use-after-free in Linux kernel's netfilter: nf_tables component
https://notcve.org/view.php?id=CVE-2023-6111
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the argument sync is true, making it possible to free a catchall set element many times. We recommend upgrading past commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630. Una vulnerabilidad de use-after-free en el componente netfilter: nf_tables del kernel de Linux puede explotarse para lograr una escalada de privilegios local. La función nft_trans_gc_catchall no eliminó el elemento del conjunto general de catchall_list cuando el argumento sync es verdadero, lo que hace posible liberar un elemento del conjunto general muchas veces. Recomendamos actualizar más allá del commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=93995bf4af2c5a99e2a87f0cd5ce547d31eb7630 https://kernel.dance/93995bf4af2c5a99e2a87f0cd5ce547d31eb7630 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3OXWBKK7RTQOGGDLQGCZFS753VLGS2GD https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3S55P23EYAWDHXZPJEVTGIRZZRICYI3Z https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IG6IF3FUY7LVZJMFRPANAU4L4PSJ3ESQ https://li • CWE-416: Use After Free •
