CVE-2022-50870

In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: avoid device tree lookups in rtasosterm rtasosterm is called during panic. Its behavior depends on a couple of conditions in the /rtas node of the device tree, the traversal of which entails locking and local IRQ...

CVE-2023-53326 powerpc: Don't try to copy PPR for task with NULL pt_regs

In the Linux kernel, the following vulnerability has been resolved: powerpc: Don't try to copy PPR for task with NULL ptregs powerpc sets up PFKTHREAD and PFIOWORKER with a NULL ptregs, which from my arguably very short checking is not commonly done for other archs. This is fine, except when...
