CVSS: 7.8EPSS: 0%CPEs: 19EXPL: 0CVE-2022-1882 – kernel: use-after-free in free_pipe_info() could lead to privilege escalation
https://notcve.org/view.php?id=CVE-2022-1882
A use-after-free flaw was found in the Linux kernel’s pipes functionality in how a user performs manipulations with the pipe post_one_notification() after free_pipe_info() that is already called. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se ha encontrado un fallo de uso después de libre en la funcionalidad de tuberías del kernel de Linux en la forma en que un usuario realiza manipulaciones con la tubería post_one_notification() después de free_pipe_info() que ya ha sido llamada. Este defecto permite a un usuario local bloquear o potencialmente escalar sus privilegios en el sistema • https://bugzilla.redhat.com/show_bug.cgi?id=2089701 https://lore.kernel.org/lkml/20220507115605.96775-1-tcs.kernel%40gmail.com/T https://security.netapp.com/advisory/ntap-20220715-0002 https://access.redhat.com/security/cve/CVE-2022-1882 • CWE-416: Use After Free •

CVSS: 7.2EPSS: 0%CPEs: 15EXPL: 0CVE-2014-0069 – kernel: cifs: incorrect handling of bogus user pointers during uncached writes
https://notcve.org/view.php?id=CVE-2014-0069
The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer. La función cifs_iovec_write en fs/cifs/file.c en el kernel de Linux hasta 3.13.5 no maneja debidamente operaciones de escritura no en caché que copian menos bytes de los solicitados, lo que permite a usuarios locales obtener información sensible de la memoria del kernel, causar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente ganar privilegios a través de una llamada al sistema writev con un puntero manipulado. • http://article.gmane.org/gmane.linux.kernel.cifs/9401 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5d81de8e8667da7135d3a32a964087c0faf5483f http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00026.html http://rhn.redhat.com/errata/RHSA-2014-0328.html http://www.openwall.com/lists/oss-security/2014/02/17/4 http://www.securityfocus.com/bid/65588 https://bugzilla.redhat.com/show_bug.cgi?id=1064253 https://github.com/torvalds/linux/comm • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
