CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2024-0562 – Kernel: use-after-free after removing device in wb_inode_writeback_end in mm/page-writeback.c
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 •

CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-6040 – An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 (netfilter: nf_tables: Reject tables of unsupported family)
https://notcve.org/view.php?id=CVE-2023-6040
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 •

https://notcve.org/view.php?id=CVE-2022-48619
An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause a denial of service (panic) because input_set_capability mishandles the situation in which an event code falls outside of a bitmap. Se descubrió un problema en drivers/input/input.c en el kernel de Linux anterior a la versión 5.17.10. Un atacante puede provocar una denegación de servicio (pánico) porque input_set_capability maneja mal la situación en la que un código de evento queda fuera de un mapa de bits.

CVSS: 5.5EPSS: 0%CPEs: 10EXPL: 0CVE-2024-0443 – Kernel: blkio memory leakage due to blkcg and some blkgs are not freed after they are made offline.
https://notcve.org/view.php?id=CVE-2024-0443
A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgroup_rstat_flush() is only called at css_release_work_fn(), which is called when the blkcg reference count reaches 0. This circular dependency will prevent blkcg and some blkgs from being freed after they are made offline. This issue may allow an attacker with a local access to cause system instability, such as an out of memory error. Se encontró un fallo en la ruta de destrucción de blkgs en block/blk-cgroup.c en el kernel de Linux, lo que provocó un problema de pérdida de memoria de cgroup blkio. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/errata/RHSA-2023:7077 https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/security/cve/CVE-2024-0443 https://bugzilla.redhat.com/show_bug.cgi?id=2257968 https://lore.kernel.org/linux-block/20221215033132.230023-3-longman@redhat.com • CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') CWE-668: Exposure of Resource to Wrong Sphere •
