An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to obtain sensitive information from heap memory via crafted frame lengths from a device. Se ha detectado un problema en el kernel de Linux versiones anteriores a 5.16.12.

https://notcve.org/view.php?id=CVE-2022-0516
A vulnerability was found in kvm_s390_guest_sida_op in the arch/s390/kvm/kvm-s390.c function in KVM for s390 in the Linux kernel. This flaw allows a local attacker with a normal user privilege to obtain unauthorized memory write access. This flaw affects Linux kernel versions prior to 5.17-rc4. Se encontró una vulnerabilidad en la función kvm_s390_guest_sida_op en el archivo arch/s390/kvm/kvm-s390.c en KVM para s390 en el kernel de Linux. Este fallo permite a un atacante local con un privilegio de usuario normal obtener un acceso de escritura en memoria no autorizado. • https://bugzilla.redhat.com/show_bug.cgi?id=2050237 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=09a93c1df3eafa43bcdfd7bf837c574911f12f55 https://security.netapp.com/advisory/ntap-20220331-0009 https://www.debian.org/security/2022/dsa-5092 https://access.redhat.com/security/cve/CVE-2022-0516 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-201: Insertion of Sensitive Information Into Sent Data •
CVSS: 7.8EPSS: 12%CPEs: 59EXPL: 31CVE-2022-0847 – Linux Kernel Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-0847
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system. Se ha encontrado un fallo en la forma en que el miembro "flags" de la estructura del nuevo búfer de la tubería carecía de la inicialización apropiada en las funciones copy_page_to_iter_pipe y push_pipe en el kernel de Linux y, por tanto, podía contener valores obsoletos. Un usuario local no privilegiado podía usar este fallo para escribir en páginas de la caché de páginas respaldadas por archivos de sólo lectura y así escalar sus privilegios en el sistema Linux versions 4.20 and above have an issue where ktls writes into spliced readonly pages. Linux kernel contains an improper initialization vulnerability where an unprivileged local user could escalate their privileges on the system. • https://www.exploit-db.com/exploits/50808 https://github.com/Arinerron/CVE-2022-0847-DirtyPipe-Exploit https://github.com/AlexisAhmed/CVE-2022-0847-DirtyPipe-Exploits https://github.com/r1is/CVE-2022-0847 https://github.com/bbaranoff/CVE-2022-0847 https://github.com/Al1ex/CVE-2022-0847 https://github.com/antx-code/CVE-2022-0847 https://github.com/basharkey/CVE-2022-0847-dirty-pipe-checker https://github.com/knqyf263/CVE-2022-0847 https://github.com/chenaotian/CVE-2022- • CWE-665: Improper Initialization CWE-909: Missing Initialization of Resource •

CVSS: 5.9EPSS: 0%CPEs: 29EXPL: 0CVE-2020-36516 – kernel: off-path attacker may inject data or terminate victim's TCP session
https://notcve.org/view.php?id=CVE-2020-36516
An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. Se ha detectado un problema en el kernel de Linux versiones hasta 5.16.11. El método de asignación de IPID mixto con la política de asignación de IPID basada en hash permite a un atacante fuera de la ruta inyectar datos en la sesión TCP de una víctima o terminar esa sesión. A TCP/IP packet spoofing attack flaw was found in the Linux kernel’s TCP/IP protocol, where a Man-in-the-Middle Attack (MITM) performs an IP fragmentation attack and an IPID collision. • https://dl.acm.org/doi/10.1145/3372297.3417884 https://security.netapp.com/advisory/ntap-20220331-0003 https://access.redhat.com/security/cve/CVE-2020-36516 https://bugzilla.redhat.com/show_bug.cgi?id=2059928 • CWE-290: Authentication Bypass by Spoofing CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
