CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2024-0646 – Kernel: ktls overwrites readonly memory pages when using function splice with a ktls socket as destination
https://notcve.org/view.php?id=CVE-2024-0646
An out-of-bounds memory write flaw was found in the Linux kernel’s Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se encontró un fallo de escritura de memoria fuera de los límites en la funcionalidad Transport Layer Security del kernel de Linux en la forma en que un usuario llama a una función splice con un socket ktls como destino. este fallo permite que un usuario local falle o potencialmente aumente sus privilegios en el sistema. • https://access.redhat.com/errata/RHSA-2024:0723 https://access.redhat.com/errata/RHSA-2024:0724 https://access.redhat.com/errata/RHSA-2024:0725 https://access.redhat.com/errata/RHSA-2024:0850 https://access.redhat.com/errata/RHSA-2024:0851 https://access.redhat.com/errata/RHSA-2024:0876 https://access.redhat.com/errata/RHSA-2024:0881 https://access.redhat.com/errata/RHSA-2024:0897 https://access.redhat.com/errata/RHSA-2024:1248 https://access.redhat.com/errata/RHSA • CWE-787: Out-of-bounds Write CWE-1314: Missing Write Protection for Parametric Data Values •

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) •
