kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of the availability of pointer arithmetic via certain *_OR_NULL pointer types. El archivo kernel/bpf/verifier.c en el kernel de Linux versiones hasta 5.15.14, permite a usuarios locales alcanzar privilegios debido a una disponibilidad de la aritmética de punteros por medio de determinados tipos de punteros *_OR_NULL A flaw was found in the Linux kernel's adjust_ptr_min_max_vals in the kernel/bpf/verifier.c function. In this flaw, a missing sanity check for *_OR_NULL pointer types that perform pointer arithmetic may cause a kernel information leak issue. • https://github.com/tr3ee/CVE-2022-23222 https://github.com/PenteraIO/CVE-2022-23222-POC https://github.com/FridayOrtiz/CVE-2022-23222 http://www.openwall.com/lists/oss-security/2022/01/14/1 http://www.openwall.com/lists/oss-security/2022/01/18/2 http://www.openwall.com/lists/oss-security/2022/06/01/1 http://www.openwall.com/lists/oss-security/2022/06/04/3 http://www.openwall.com/lists/oss-security/2022/06/07/3 https://bugzilla.suse.com/show_ • CWE-476: NULL Pointer Dereference CWE-763: Release of Invalid Pointer or Reference •

https://notcve.org/view.php?id=CVE-2021-3743
An out-of-bounds (OOB) memory read flaw was found in the Qualcomm IPC router protocol in the Linux kernel. A missing sanity check allows a local attacker to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. Se ha encontrado un defecto de lectura de memoria fuera de límites (OOB) en el protocolo de router Qualcomm IPC en el kernel de Linux. Una falta de comprobación de saneo permite a un atacante local conseguir acceso de memoria fuera de límites, conllevando a un bloqueo del sistema o un filtrado de información interna del kernel. • https://bugzilla.redhat.com/show_bug.cgi?id=1997961 https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=7e78c597c3eb https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7e78c597c3ebfd0cb329aa09a838734147e4f117 https://github.com/torvalds/linux/commit/7e78c597c3ebfd0cb329aa09a838734147e4f117 https://lists.openwall.net/netdev/2021/08/17/124 https://security.netapp.com/advisory/ntap-20220407-0007 https://www.openwall.com/lists/oss-security/2021/08/27 • CWE-125: Out-of-bounds Read •

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 •
