https://notcve.org/view.php?id=CVE-2024-0639
A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in net/sctp/socket.c in the Linux kernel’s SCTP subsystem. This flaw allows guests with local user privileges to trigger a deadlock and potentially crash the system. Se encontró una vulnerabilidad de denegación de servicio debido a un punto muerto en sctp_auto_asconf_init en net/sctp/socket.c en el subsistema SCTP del kernel de Linux. Esta falla permite a los invitados con privilegios de usuario local desencadenar un punto muerto y potencialmente bloquear el sistema. • https://access.redhat.com/security/cve/CVE-2024-0639 https://bugzilla.redhat.com/show_bug.cgi?id=2258754 https://github.com/torvalds/linux/commit/6feb37b3b06e9049e20dcf7e23998f92c9c5be9a • CWE-667: Improper Locking CWE-833: Deadlock •

A memory leak flaw was found in the Linux kernel’s io_uring functionality in how a user registers a buffer ring with IORING_REGISTER_PBUF_RING, mmap() it, and then frees it. This flaw allows a local user to crash or potentially escalate their privileges on the system.

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) •

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.

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 •
