CVE-2022-39190 – kernel: nf_tables disallow binding to already bound chain
https://notcve.org/view.php?id=CVE-2022-39190
An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of service can occur upon binding to an already bound chain. Se ha detectado un problema en el archivo net/netfilter/nf_tables_api.c en el kernel de Linux versiones anteriores a 5.19.6. Puede producirse una denegación de servicio al vincularse a una cadena ya vinculada A flaw was found in net/netfilter/nf_tables_api.c in the Linux kernel. A denial of service can occur upon binding to an already bound chain. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.19.6 https://github.com/torvalds/linux/commit/e02f0d3970404bfea385b6edb86f2d936db0ea2b https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://lore.kernel.org/all/20220824220330.64283-12-pablo%40netfilter.org https://twitter.com/pr0Ln https://access.redhat.com/security/cve/CVE-2022-39190 https://bugzilla.redhat.com/show_bug.cgi?id=2129152 • CWE-392: Missing Report of Error Condition •
CVE-2022-2590
https://notcve.org/view.php?id=CVE-2022-2590
A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only shared memory mappings. This flaw allows an unprivileged, local user to gain write access to read-only memory mappings, increasing their privileges on the system. Se encontró una condición de carrera en la forma en que el subsistema de memoria del kernel de Linux manejaba la ruptura de copia en escritura (COW) de las asignaciones de memoria compartida privada de sólo lectura. Este fallo permite a un usuario local no privilegiado conseguir acceso de escritura a las asignaciones de memoria de sólo lectura, aumentando sus privilegios en el sistema • https://github.com/hyeonjun17/CVE-2022-2590-analysis https://lore.kernel.org/linux-mm/20220808073232.8808-1-david%40redhat.com https://www.openwall.com/lists/oss-security/2022/08/08/1 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2022-3028 – kernel: race condition in xfrm_probe_algs can lead to OOB read/write
https://notcve.org/view.php?id=CVE-2022-3028
A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. Se ha encontrado una condición de carrera en el marco IP del kernel de Linux para la transformación de paquetes (subsistema XFRM) cuando son producidas simultáneamente varias llamadas a xfrm_probe_algs. Este fallo podría permitir a un atacante local desencadenar potencialmente una escritura fuera de límites o una pérdida de memoria de la pila del kernel al llevar a cabo una lectura fuera de límites y copiarla en un socket • https://github.com/torvalds/linux/commit/ba953a9d89a00c078b85f4b190bc1dde66fe16b5 https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F3MYP7WX4PNE6RCITVXA43CECBZT4CL6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JKVA75UHKVOHNOEPCLUHTFGWCOOUBDM3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraprojec • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-667: Improper Locking CWE-787: Out-of-bounds Write •
CVE-2022-2961
https://notcve.org/view.php?id=CVE-2022-2961
A use-after-free flaw was found in the Linux kernel’s PLP Rose functionality in the way a user triggers a race condition by calling bind while simultaneously triggering the rose_bind() function. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se ha encontrado un fallo de uso de memoria previamente liberada en la funcionalidad PLP Rose del kernel de Linux en la forma en que un usuario desencadena una condición de carrera al llamar a bind mientras es desencadenada simultáneamente la función rose_bind().

A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use this flaw to crash the system or potentially escalate their privileges on the system. Se encontró un fallo de uso de memoria previamente liberada en el sistema de archivos NILFS del kernel de Linux en la forma en que el usuario desencadena la función security_inode_alloc para que falle con la siguiente llamada a la función nilfs_mdt_destroy.
