Descriptions

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.

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.

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. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
