Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue concerns preventing nullptr exceptions on ISR in the Linux kernel. Specifically, it involves checking for a valid interrupt handler when phydev-irq is set unconditionally, or...

PT-2024-21510

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to a potential deadlock at set capacity in the Linux kernel. This occurs due to an interrupt unsafe locking scenario where aoeblk gdalloc holds &d-lock and attempts ...

The vulnerability of NVIDIA’s SBIOS system, specifically the DGX A100 server, allows a hacker to gain access to read, modify, or delete data. This can enable the hacker to increase their privileges, execute arbitrary code, or cause a service failure.

The vulnerability of the SBIOS system’s NVIDIA DGX A100 server stems from the transition to System Management Mode SMM due to an SMI interrupt. Exploiting this vulnerability can allow an attacker to gain read, modify, or delete data access rights, enhance their privileges, execute arbitrary code,...
