CVE-2023-52683

En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: ACPI: LPIT: Evitar desbordamiento de multiplicación u32 En lpit_update_residency() existe la posibilidad de desbordamiento en la multiplicación, si tsc_khz es lo suficientemente grande (> UINT_MAX/1000). Cambie la multiplicación a mul_u32_u32(). Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.

In the Linux kernel, the following vulnerability has been resolved: ACPI: LPIT: Avoid u32 multiplication overflow In lpit_update_residency() there is a possibility of overflow in multiplication, if tsc_khz is large enough (> UINT_MAX/1000). Change multiplication to mul_u32_u32(). Found by Linux Verification Center (linuxtesting.org) with SVACE.

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service. Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service.
