CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 9CVE-2022-2588 – Linux Kernel route4_change Double Free Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-2588
It was discovered that the cls_route filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it if its handle had the value 0. Se descubrió que la implementación del filtro cls_route en el kernel de Linux no eliminaba un filtro antiguo de la tabla hash antes de liberarlo si su identificador tenía el valor 0. A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege escalation problem. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. • https://github.com/Markakd/CVE-2022-2588 https://github.com/veritas501/CVE-2022-2588 https://github.com/BassamGraini/CVE-2022-2588 https://github.com/PolymorphicOpcode/CVE-2022-2588 https://github.com/dom4570/CVE-2022-2588 https://github.com/ASkyeye/2022-LPE-UAF https://github.com/pirenga/2022-LPE-UAF https://github.com/konoha279/2022-LPE-UAF https://github.com/snackbauer/CVE-2022-2588 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2588 https://lore. • CWE-415: Double Free CWE-416: Use After Free •

The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges. El kernel de Linux versiones anteriores a 5.18.13, carece de una determinada operación de borrado para el símbolo de inicio de bloque (.bss). Esto permite a usuarios del SO huésped Xen PV causar una denegación de servicio o conseguir privilegios • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.18.13 https://github.com/sickcodes/security/blob/master/advisories/SICK-2022-128.md https://github.com/torvalds/linux/commit/74a0032b8524ee2bd4443128c0bf9775928680b0 https://github.com/torvalds/linux/commit/96e8fc5818686d4a1591bb6907e7fdb64ef29884 https://security.netapp.com/advisory/ntap-20220901-0003 https://sick.codes/sick-2022-128 •

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 •

https://notcve.org/view.php?id=CVE-2022-36946
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. This flaw allows a local user to crash the system or a remote user to crash the system when the libnetfilter_queue is used by a local user. • https://github.com/Pwnzer0tt1/CVE-2022-36946 https://github.com/Satheesh575555/linux-4.19.72_CVE-2022-36946 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=99a63d36cb3ed5ca3aa6fcb64cffbeaf3b0fb164 https://lists.debian.org/debian-lts-announce/2022/09/msg00011.html https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://marc.info/?l=netfilter-devel&m=165883202007292&w=2 https://security.netapp.com/advisory/ntap-20220901-0007 https://www.debian&# •
