CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 2CVE-2022-2586 – Linux Kernel Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2022-2586
It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted. Se descubrió que un objeto o expresión nft podía hacer referencia a un conjunto nft en una tabla nft diferente, lo que generaba un use-after-free una vez que se eliminaba esa tabla. A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. • https://github.com/aels/CVE-2022-2586-LPE https://github.com/sniper404ghostxploit/CVE-2022-2586 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2586 https://lore.kernel.org/netfilter-devel/20220809170148.164591-1-cascardo@canonical.com/T/#t https://ubuntu.com/security/notices/USN-5557-1 https://ubuntu.com/security/notices/USN-5560-1 https://ubuntu.com/security/notices/USN-5560-2 https://ubuntu.com/security/notices/USN-5562-1 https://ubuntu.com/security/notices&# • CWE-416: Use After Free •

Linux deployments of StorageGRID (formerly StorageGRID Webscale) versions 11.6.0 through 11.6.0.2 deployed with a Linux kernel version less than 4.7.0 are susceptible to a vulnerability which could allow a remote unauthenticated attacker to view limited metrics information and modify alert email recipients and content. Las implantaciones en Linux de StorageGRID (anteriormente conocido como StorageGRID Webscale) versiones 11.6.0 hasta 11.6.0.2 implantadas con una versión del kernel de Linux inferior a 4.7.0 son susceptibles de una vulnerabilidad que podría permitir a un atacante remoto no autenticado visualizar información de métricas limitada y modificar los destinatarios y el contenido de los correos electrónicos de alerta • https://security.netapp.com/advisory/NTAP-20220808-0001 •
CVSS: 5.5EPSS: 0%CPEs: 22EXPL: 0CVE-2022-1184 – kernel: use-after-free and memory errors in ext4 when mounting and operating on a corrupted image
https://notcve.org/view.php?id=CVE-2022-1184
A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel’s filesystem sub-component. This flaw allows a local attacker with a user privilege to cause a denial of service. Se ha detectado un fallo de uso de memoria previamente liberada en el archivo fs/ext4/namei.c:dx_insert_block() en el subcomponente del sistema de archivos del kernel de Linux. Este fallo permite a un atacante local con privilegios de usuario causar una denegación de servicio • https://access.redhat.com/security/cve/CVE-2022-1184 https://bugzilla.redhat.com/show_bug.cgi?id=2070205 https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://ubuntu.com/security/CVE-2022-1184 https://www.debian.org/security/2022/dsa-5257 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 22EXPL: 9CVE-2022-34918 – kernel: heap overflow in nft_set_elem_init()
https://notcve.org/view.php?id=CVE-2022-34918
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.9. • https://github.com/veritas501/CVE-2022-34918 https://github.com/randorisec/CVE-2022-34918-LPE-PoC https://github.com/merlinepedra25/CVE-2022-34918-LPE-PoC https://github.com/merlinepedra/CVE-2022-34918-LPE-PoC https://github.com/linulinu/CVE-2022-34918 http://packetstormsecurity.com/files/168191/Kernel-Live-Patch-Security-Notice-LSN-0089-1.html http://packetstormsecurity.com/files/168543/Netfilter-nft_set_elem_init-Heap-Overflow-Privilege-Escalation.html http://www.openwall.com/lists/oss-secur • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') CWE-1025: Comparison Using Wrong Factors •
