CVE-2021-47421

CVE-2021-47421 affects the Linux kernel amdgpu driver. The root cause is that during PCI error handling, the code may release a write lock in amdgpu_pci_resume even when not safely holding it, leading to potential deadlocks when other threads acquire a read lock. The fix, documented across connec...

CVE-2021-47362 drm/amd/pm: Update intermediate power state for SI

In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: Update intermediate power state for SI Update the current state as boot state during dpm initialization. During the subsequent initialization, setpowerstate gets called to transition to the final power state...

CVE-2021-47362

CVE-2021-47362 affects the Linux kernel’s drm/amd/pm power management code. The vulnerability occurs during DPM initialization when set_power_state reads values from the current state; if current state is not populated, this can lead to a NULL pointer dereference. The ATCS/ACPI path for PCI speed...

CVE-2021-47235

CVE-2021-47235 affects the Linux kernel net/ethernet path: ec_bhf_remove() uses priv (netdev private data) after free_netdev() is called, enabling a use-after-free. The fixed sequence moves free_netdev() to occur after the PCI I/O unmaps (pci_iounmap) of priv, preventing access to freed memory. D...
