crash). (CVE-2023-23004)
It was discovered that a race condition existed in the TLS subsystem in the
Linux kernel, leading to a use-after-free or a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-28466)
It was discovered that the DA9150 charger driver in the Linux kernel did
not properly handle device removal, leading to a user-after free
vulnerability. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-30772)
It was discovered that the Ricoh R5C592 MemoryStick card reader driver in
the Linux kernel contained a race condition during module unload, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-3141)
Quentin Minster discovered that the KSMBD implementation in the Linux
kernel did not properly validate pointers in some situations, leading to a
null pointer dereference vulnerability. A remote attacker could use this to
cause a denial of service (system crash). (CVE-2023-32248)
It was discovered that the kernel->user space relay implementation in the
Linux kernel did not properly perform certain buffer calculations, leading
to an out-of-bounds read vulnerability. A local attacker could use this to
cause a denial of service (system crash) or expose sensitive information
(kernel memory). (CVE-2023-3268)
