CVE-2024-26661

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: agregue prueba NULL para 'generador de sincronización' en 'dcn21_set_pipe()' en "u32 otg_inst = pipe_ctx->stream_res.tg->inst;" pipe_ctx->stream_res.tg podría ser NULL, depende de la persona que llama garantizar que el tg no sea NULL.

A NULL pointer dereference flaw was found in the Linux kernel in dcn21_set_pipe(). This issue may lead to a crash.

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add NULL test for 'timing generator' in 'dcn21_set_pipe()' In "u32 otg_inst = pipe_ctx->stream_res.tg->inst;" pipe_ctx->stream_res.tg could be NULL, it is relying on the caller to ensure the tg is not NULL.

It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service or possibly expose sensitive information. Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service or possibly execute arbitrary code.
