Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. El Kernel de Linux podría permitir a un atacante local ejecutar código arbitrario en el sistema, causado por un fallo de uso de memoria previamente liberada concurrente en la función bad_flp_intr. Al ejecutar un programa especialmente diseñado, un atacante podría explotar esta vulnerabilidad para ejecutar código arbitrario o causar una condición de denegación de servicio en el sistema • https://bugzilla.redhat.com/show_bug.cgi?id=1832397 https://francozappa.github.io/about-bias https://kb.cert.org/vuls/id/647177 https://security.netapp.com/advisory/ntap-20220722-0002 https://www.debian.org/security/2022/dsa-5173 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2022-1419
The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will access the freed drm_vgem_gem_object. La causa principal de esta vulnerabilidad es que el ioctl$DRM_IOCTL_MODE_DESTROY_DUMB puede disminuir el refcount de *drm_vgem_gem_object *(creado en *vgem_gem_dumb_create*) simultáneamente, y *vgem_gem_dumb_create *accederá al drm_vgem_gem_object liberado • https://bugzilla.redhat.com/show_bug.cgi?id=2077560 https://www.debian.org/security/2022/dsa-5173 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2022-0168
A denial of service (DOS) issue was found in the Linux kernel’s smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system. Se encontró un problema de denegación de servicio (DOS) en la función smb2_ioctl_query_info del kernel de Linux en el archivo fs/cifs/smb2ops.c Common Internet File System (CIFS) debido a un retorno incorrecto de la función memdup_user. Este fallo permite a un atacante local privilegiado (CAP_SYS_ADMIN) bloquear el sistema. • https://access.redhat.com/security/cve/CVE-2022-0168 https://bugzilla.redhat.com/show_bug.cgi?id=2037386 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6f5e358452479fa8a773b5c6ccc9e4ec5a20880 • CWE-476: NULL Pointer Dereference •
