CVSS: 4.4EPSS: 0%CPEs: 3EXPL: 0CVE-2022-0168 – kernel: smb2_ioctl_query_info NULL pointer dereference
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 •
