  script_tag(name:"insight", value:"Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel
did not properly validate certain data structure fields when parsing lease
contexts, leading to an out-of-bounds read vulnerability. A remote attacker
could use this to cause a denial of service (system crash) or possibly
expose sensitive information. (CVE-2023-1194)

Quentin Minster discovered that a race condition existed in the KSMBD
implementation in the Linux kernel, leading to a use-after-free
vulnerability. A remote attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2023-32254)

It was discovered that a race condition existed in the KSMBD implementation
in the Linux kernel when handling session connections, leading to a use-
after-free vulnerability. A remote attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-32258)

It was discovered that the KSMBD implementation in the Linux kernel did not
properly validate buffer sizes in certain operations, leading to an integer
underflow and out-of-bounds read vulnerability. A remote attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2023-38427)

Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel
did not properly validate SMB request protocol IDs, leading to a out-of-
bounds read vulnerability. A remote attacker could possibly use this to
cause a denial of service (system crash). (CVE-2023-38430)

Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel
did not properly validate packet header sizes in certain situations,
leading to an out-of-bounds read vulnerability. A remote attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2023-38431)

It was discovered that the KSMBD implementation in the Linux kernel did not
properly handle session setup requests, leading to an out-of-bounds read
vulnerability. A remote attacker could use this to expose sensitive
information. (CVE-2023-3867)

Pratyush Yadav discovered that the Xen network backend implementation in
the Linux kernel did not properly handle zero length data request, leading
to a null pointer dereference vulnerability. An attacker in a guest VM
could possibly use this to cause a denial of service (host domain crash).
(CVE-2023-46838)

It was discovered that the IPv6 implementation of the Linux kernel did not
properly manage route cache memory usage. A remote attacker could use this
to cause a denial of service (memory exhaustion). (CVE-2023-52340)

It was discovered that the device mapper driver in the Linux kernel did not
properly validate target size during certain memory allocations. A local
attacker could use this to cause a denial of service (system crash).
