CVE-2022-0995 – Watch Queue Out-Of-Bounds Write
https://notcve.org/view.php?id=CVE-2022-0995
An out-of-bounds (OOB) memory write flaw was found in the Linux kernel’s watch_queue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system. Se encontró un fallo de escritura en memoria fuera de límites (OOB) en el subsistema de notificación de eventos watch_queue del kernel de Linux. este fallo puede sobrescribir partes del estado del kernel, permitiendo potencialmente a un usuario local conseguir acceso privilegiado o causar una denegación de servicio en el sistema The Linux watch_queue filter suffers from an out of bounds write vulnerability. • https://github.com/Bonfee/CVE-2022-0995 https://github.com/1nzag/CVE-2022-0995 https://github.com/AndreevSemen/CVE-2022-0995 http://packetstormsecurity.com/files/166770/Linux-watch_queue-Filter-Out-Of-Bounds-Write.html http://packetstormsecurity.com/files/166815/Watch-Queue-Out-Of-Bounds-Write.html https://bugzilla.redhat.com/show_bug.cgi?id=2063786 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=93ce93587d36493f2f86921fa79921b3cba63fbb https://security.netapp.com • CWE-787: Out-of-bounds Write •
CVE-2022-0494 – kernel: information leak in scsi_ioctl()
https://notcve.org/view.php?id=CVE-2022-0494
A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. Se ha identificado un fallo de filtrado de información del kernel en la función scsi_ioctl en el archivo drivers/scsi/scsi_ioctl.c en el kernel de Linux. este fallo permite a un atacante local con un privilegio de usuario especial (CAP_SYS_ADMIN o CAP_SYS_RAWIO) crear problemas de confidencialidad • https://bugzilla.redhat.com/show_bug.cgi?id=2039448 https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://lore.kernel.org/all/20220216084038.15635-1-tcs.kernel%40gmail.com https://www.debian.org/security/2022/dsa-5161 https://www.debian.org/security/2022/dsa-5173 https://access.redhat.com/security/cve/CVE-2022-0494 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource •

CVE-2022-27666 – kernel: buffer overflow in IPsec ESP transformation code
https://notcve.org/view.php?id=CVE-2022-27666
A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. Se ha encontrado un fallo de desbordamiento del búfer de la pila en el código de transformación de IPsec ESP en net/ipv4/esp4.c y net/ipv6/esp6.c.

CVE-2022-0742 – Memory leak in ICMP6 in Linux Kernel
https://notcve.org/view.php?id=CVE-2022-0742
Memory leak in icmp6 implementation in Linux Kernel 5.13+ allows a remote attacker to DoS a host by making it go out-of-memory via icmp6 packets of type 130 or 131. We recommend upgrading past commit 2d3916f3189172d5c69d33065c3c21119fe539fc. Una pérdida de memoria en la implementación de icmp6 en el Kernel de Linux versión 5.13+, permite a un atacante remoto hacer DoS a un host haciendo que salga de la memoria por medio de paquetes icmp6 de tipo 130 o 131.
