A flaw was found in the filelock_init in fs/locks.c function in the Linux kernel. This issue can lead to host memory exhaustion due to memcg not limiting the number of Portable Operating System Interface (POSIX) file locks. Se ha encontrado un fallo en la función filelock_init en el archivo fs/locks.c del kernel de Linux. Este problema puede conllevar a un agotamiento de la memoria del host debido a que memcg no limita el número de bloqueos de archivos de la Interfaz del Sistema Operativo Portátil (POSIX) • https://access.redhat.com/security/cve/CVE-2022-0480 https://bugzilla.redhat.com/show_bug.cgi?id=2049700 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0f12156dff2862ac54235fc72703f18770769042 https://github.com/kata-containers/kata-containers/issues/3373 https://lore.kernel.org/linux-mm/20210902215519.AWcuVc3li%25akpm%40linux-foundation.org https://ubuntu.com/security/CVE-2022-0480 • CWE-770: Allocation of Resources Without Limits or Throttling •

A use-after-free flaw was found in the Linux kernel’s PLP Rose functionality in the way a user triggers a race condition by calling bind while simultaneously triggering the rose_bind() function. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se ha encontrado un fallo de uso de memoria previamente liberada en la funcionalidad PLP Rose del kernel de Linux en la forma en que un usuario desencadena una condición de carrera al llamar a bind mientras es desencadenada simultáneamente la función rose_bind().

A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD CPU that supports Secure Encrypted Virtualization (SEV). Se ha encontrado un fallo en el kernel de Linux. La API existente de KVM SEV presenta una vulnerabilidad que permite que una aplicación a nivel de usuario no root (anfitrión) bloquee el kernel del anfitrión al crear una instancia de VM de invitado confidencial en la CPU de AMD que admite la virtualización cifrada segura (SEV). • https://access.redhat.com/security/cve/CVE-2022-0171 https://bugzilla.redhat.com/show_bug.cgi?id=2038940 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=683412ccf61294d727ead4a73d97397396e69a6b https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://www.debian.org/security/2022/dsa-5257 • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer CWE-459: Incomplete Cleanup •

A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. Se encontró una vulnerabilidad en el verificador EBPF del kernel de Linux cuando son manejadas estructuras de datos internas. Las ubicaciones de memoria interna podían ser devueltas al espacio de usuario. • https://access.redhat.com/security/cve/CVE-2021-4159 https://bugzilla.redhat.com/show_bug.cgi?id=2036024 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=294f2fc6da27620a506e6c050241655459ccd6bd https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security-tracker.debian.org/tracker/CVE-2021-4159 • CWE-202: Exposure of Sensitive Information Through Data Queries •
