https://notcve.org/view.php?id=CVE-2022-29526
Go before 1.17.10 and 1.18.x before 1.18.2 has Incorrect Privilege Assignment. When called with a non-zero flags parameter, the Faccessat function could incorrectly report that a file is accessible. Go versiones anteriores a 1.17.10 y 1.18.x anteriores a 1.18.2, presenta una Asignación Incorrecta de Privilegios. Cuando es llamada con un parámetro flags distinto de cero, la función Faccessat podría informar incorrectamente de que un archivo es accesible A flaw was found in the syscall.Faccessat function when calling a process by checking the group. This flaw allows an attacker to check the process group permissions rather than a member of the file's group, affecting system availability. • https://github.com/golang/go/issues/52313 https://groups.google.com/g/golang-announce https://groups.google.com/g/golang-announce/c/Y5qrqw_lWdU https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Q6GE5EQGE4L2KRVGW4T75QVIYAXCLO5X https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RQXU752ALW53OJAF5MG3WMR5CCZVLWW6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z55VUVGO7E5PJFXIOVAY373NZRHBNCI5 https://lists&# • CWE-269: Improper Privilege Management CWE-280: Improper Handling of Insufficient Permissions or Privileges •

CVSS: 8.8EPSS: 0%CPEs: 22EXPL: 6CVE-2022-32250 – Linux Kernel nf_tables_expr_destroy Use-After-Free Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-32250
net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. El archivo net/netfilter/nf_tables_api.c en el kernel de Linux versiones hasta 5.18.1, permite a un usuario local (capaz de crear espacios de nombres de usuario/red) escalar privilegios a root porque una comprobación incorrecta de NFT_STATEFUL_EXPR conlleva a un uso de memoria previamente liberada A use-after-free vulnerability was found in the Linux kernel's Netfilter subsystem in net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege escalation issue. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the nf_tables_expr_destroy method. • https://github.com/theori-io/CVE-2022-32250-exploit https://github.com/ysanatomic/CVE-2022-32250-LPE https://github.com/Kristal-g/CVE-2022-32250 http://www.openwall.com/lists/oss-security/2022/06/03/1 http://www.openwall.com/lists/oss-security/2022/06/04/1 http://www.openwall.com/lists/oss-security/2022/06/20/1 http://www.openwall.com/lists/oss-security/2022/07/03/5 http://www.openwall.com/lists/oss-security/2022/07/03/6 http://www.openwall&# • CWE-416: Use After Free •
