CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-50112 – x86/lam: Disable ADDRESS_MASKING in most cases
https://notcve.org/view.php?id=CVE-2024-50112
In the Linux kernel, the following vulnerability has been resolved: x86/lam: Disable ADDRESS_MASKING in most cases Linear Address Masking (LAM) has a weakness related to transient execution as described in the SLAM paper[1]. Unless Linear Address Space Separation (LASS) is enabled this weakness may be exploitable. Until kernel adds support for LASS[2], only allow LAM for COMPILE_TEST, or when speculation mitigations have been disabled at compile time, otherwise keep LAM disabled. There are no processors in market that support LAM yet, so currently nobody is affected by this issue. [1] SLAM: https://download.vusec.net/papers/slam_sp24.pdf [2] LASS: https://lore.kernel.org/lkml/20230609183632.48706-1-alexander.shishkin@linux.intel.com/ [ dhansen: update SPECULATION_MITIGATIONS -> CPU_MITIGATIONS ] En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: x86/lam: Deshabilitar ADDRESS_MASKING en la mayoría de los casos. El enmascaramiento de direcciones lineales (LAM) tiene una debilidad relacionada con la ejecución transitoria como se describe en el documento SLAM[1]. A menos que se habilite la separación del espacio de direcciones lineales (LASS), esta debilidad puede ser explotable. Hasta que el kernel agregue soporte para LASS[2], solo permita LAM para COMPILE_TEST, o cuando las mitigaciones de especulación se hayan deshabilitado en el momento de la compilación, de lo contrario, mantenga LAM deshabilitado. • https://git.kernel.org/stable/c/60a5ba560f296ad8da153f6ad3f70030bfa3958f https://git.kernel.org/stable/c/690599066488d16db96ac0d6340f9372fc56f337 https://git.kernel.org/stable/c/3267cb6d3a174ff83d6287dcd5b0047bbd912452 •

https://notcve.org/view.php?id=CVE-2024-50108
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Disable PSR-SU on Parade 08-01 TCON too Stuart Hayhurst has found that both at bootup and fullscreen VA-API video is leading to black screens for around 1 second and kernel WARNING [1] traces when calling dmub_psr_enable() with Parade 08-01 TCON. These symptoms all go away with PSR-SU disabled for this TCON, so disable it for now while DMUB traces [2] from the failure can be analyzed and the failure state properly root caused. (cherry picked from commit afb634a6823d8d9db23c5fb04f79c5549349628b) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Deshabilitar PSR-SU también en Parade 08-01 TCON Stuart Hayhurst ha descubierto que tanto en el arranque como en pantalla completa, el vídeo VA-API provoca pantallas negras durante alrededor de 1 segundo y rastros de ADVERTENCIA [1] en el kernel al llamar a dmub_psr_enable() con Parade 08-01 TCON. Todos estos síntomas desaparecen con PSR-SU deshabilitado para este TCON, así que deshabilítelo por ahora mientras se pueden analizar los rastros DMUB [2] del fallo y se puede determinar correctamente el estado del fallo.
