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 •

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 •
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 •

A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
