CVSS: 8.3EPSS: 0%CPEs: 7EXPL: 0CVE-2024-0565 – Kernel: cifs filesystem decryption improper input validation remote code execution vulnerability in function receive_encrypted_standard of client
https://notcve.org/view.php?id=CVE-2024-0565
An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service. Se encontró un fallo de lectura de memoria fuera de los límites en receive_encrypted_standard en fs/smb/client/smb2ops.c en el subcomponente SMB Client en el kernel de Linux. Este problema se produce debido a un desbordamiento insuficiente de enteros en la longitud de memcpy, lo que provoca una denegación de servicio. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Kernel. • https://access.redhat.com/errata/RHSA-2024:1188 https://access.redhat.com/errata/RHSA-2024:1404 https://access.redhat.com/errata/RHSA-2024:1532 https://access.redhat.com/errata/RHSA-2024:1533 https://access.redhat.com/errata/RHSA-2024:1607 https://access.redhat.com/errata/RHSA-2024:1614 https://access.redhat.com/errata/RHSA-2024:2093 https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/security/cve/CVE-2024-0565 https://bugzilla.redhat.com/show • CWE-191: Integer Underflow (Wrap or Wraparound) •

https://notcve.org/view.php?id=CVE-2024-0562
A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdi_unregister is called to stop further write-back and waits for associated delayed work to complete. However, wb_inode_writeback_end() may schedule bandwidth estimation work after this has completed, which can result in the timer attempting to access the recently freed bdi_writeback. Se encontró un fallo de use after free en el kernel de Linux. Cuando se elimina un disco, se llama a bdi_unregister para detener la reescritura adicional y espera a que se complete el trabajo retrasado asociado. • https://access.redhat.com/errata/RHSA-2024:0412 https://access.redhat.com/security/cve/CVE-2024-0562 https://bugzilla.redhat.com/show_bug.cgi?id=2258475 https://patchwork.kernel.org/project/linux-mm/patch/20220801155034.3772543-1-khazhy@google.com • CWE-416: Use After Free •

A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may allow an attacker using this library to cause a denial of service problem due to a missing check at a function return. Se encontró un problema de desreferencia de puntero null en ida_free en lib/idr.c en el kernel de Linux. Este problema puede permitir que un atacante que utilice esta librería cause un problema de denegación de servicio debido a una verificación faltante en el retorno de una función. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-6915 https://bugzilla.redhat.com/show_bug.cgi?id=2254982 https://github.com/torvalds/linux/commit/af73483f4e8b6f5c68c9aa63257bdd929a9c194a https://lists.debian.org/debian-lts-announce/2024/06/msg00016.html • CWE-476: NULL Pointer Dereference •

An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an attacker to achieve out-of-bounds access. Se informó y solucionó una vulnerabilidad de acceso fuera de los límites que involucraba a netfilter como: f1082dd31fe4 (netfilter: nf_tables: Rechazar tablas de familia no admitida); Al crear una nueva tabla netfilter, la falta de protección contra valores no válidos de la familia nf_tables (pf) dentro de la función `nf_tables_newtable` permite a un atacante lograr un acceso fuera de los límites. An out-of-bounds access vulnerability was found in the Linux Kernel. This issue occurs during the creation of a new netfilter table. The absence of safeguards in the nf_tables_newtable function against invalid nf_tables family (pf) values allows attackers to achieve unauthorized access. • http://packetstormsecurity.com/files/177029/Kernel-Live-Patch-Security-Notice-LSN-0100-1.html http://www.openwall.com/lists/oss-security/2024/01/12/1 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-6040 https://lists.debian.org/debian-lts-announce/2024/06/msg00016.html https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html https://www.openwall.com/lists/oss-security/2024/01/12/1 https://access.redhat.com/security/cve/CVE-2023-6040 https://bugzilla& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
