An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.14. la función xfrm_expand_policies en el archivo net/xfrm/xfrm_policy.c puede causar que un refcount sea descartado dos veces A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). An error while resolving policies in xfrm_bundle_lookup causes the refcount to drop twice, leading to a possible crash and a denial of service. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=f85daf0e725358be78dfd208dea5fd665d8cb901 https://github.com/torvalds/linux/commit/f85daf0e725358be78dfd208dea5fd665d8cb901 https://lists.debian.org/debian-lts-announce/2022/09/msg00011.html https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security.netapp.com/advisory/ntap-20220901-0007 https://www.debian.org/security/2022/dsa-5207 https://access.redhat.com/security/cve/CVE-2022-36879 https://bugzilla.r • CWE-911: Improper Update of Reference Count •

nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. La función nfqnl_mangle en el archivo net/netfilter/nfnetlink_queue.c en el kernel de Linux versiones hasta 5.18.14, permite a atacantes remotos causar una denegación de servicio (pánico) porque, en el caso de un veredicto nf_queue con un atributo nfta_payload de un byte, un skb_pull puede encontrar un skb-)len negativo A memory corruption flaw was found in the Linux kernel’s Netfilter subsystem in the way a local user uses the libnetfilter_queue when analyzing a corrupted network packet.
