An issue was discovered in the Linux kernel through 5.16-rc6. There is a lack of check after calling vzalloc() and lack of free after allocation in drivers/media/test-drivers/vidtv/vidtv_s302m.c. Se ha detectado un problema en el kernel de Linux versiones hasta 5.16-rc6.

CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 4CVE-2022-2639 – kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size()
https://notcve.org/view.php?id=CVE-2022-2639
An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se ha encontrado un error de coerción de enteros en el módulo del kernel openvswitch. Dado un número suficientemente grande de acciones, mientras ses copiado y es reservada memoria para una nueva acción de un nuevo flujo, la función reserve_sfa_size() no devuelve -EMSGSIZE como es esperado, conllevando potencialmente a un acceso de escritura fuera de límites. • https://github.com/bb33bb/CVE-2022-2639-PipeVersion https://github.com/letsr00t/-2022-LOCALROOT-CVE-2022-2639 https://github.com/EkamSinghWalia/Detection-and-Mitigation-for-CVE-2022-2639 https://bugzilla.redhat.com/show_bug.cgi?id=2084479 https://github.com/torvalds/linux/commit/cefa91b2332d7009bc0be5d951d6cbbf349f90f8 https://access.redhat.com/security/cve/CVE-2022-2639 • CWE-192: Integer Coercion Error CWE-681: Incorrect Conversion between Numeric Types •

A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl() printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had been freed by gprinter_free(). Se encontró una vulnerabilidad en el kernel de Linux, donde al acceder a una instancia desasignada en printer_ioctl() printer_ioctl() intenta acceder a una instancia de printer_dev. Sin embargo, es producido un uso de memoria previamente liberada porque había sido liberada por la función gprinter_free() • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e8d5f92b8d30bb4ade76494490c3c065e12411b1 • CWE-201: Insertion of Sensitive Information Into Sent Data CWE-416: Use After Free •

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 •
