CVE-2022-48770 – bpf: Guard against accessing NULL pt_regs in bpf_get_task_stack()
https://notcve.org/view.php?id=CVE-2022-48770
20 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: bpf: Guard against accessing NULL pt_regs in bpf_get_task_stack() task_pt_regs() can return NULL on powerpc for kernel threads. This is then used in __bpf_get_stack() to check for user mode, resulting in a kernel oops. Guard against this by checking return value of task_pt_regs() before trying to obtain the call chain. In the Linux kernel, the following vulnerability has been resolved: bpf: Guard against accessing NULL pt_regs in bpf_get_ta... • https://git.kernel.org/stable/c/fa28dcb82a38f8e3993b0fae9106b1a80b59e4f0 •
CVE-2022-48769 – efi: runtime: avoid EFIv2 runtime services on Apple x86 machines

20 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: efi: runtime: avoid EFIv2 runtime services on Apple x86 machines Aditya reports [0] that his recent MacbookPro crashes in the firmware when using the variable services at runtime. The culprit appears to be a call to QueryVariableInfo(), which we did not use to call on Apple x86 machines in the past as they only upgraded from EFI v1.10 to EFI v2.40 firmware fairly recently, and QueryVariableInfo() (along with UpdateCapsule() et al) was added... • https://git.kernel.org/stable/c/b0f1cc093bc2493ac259c53766fd2b800e085807 •

If userspace forces the vCPU out of SMM while it's post-VMXON and then injects an SMI, vmx_enter_smm() will overwrite vmx->nested.smm.vmxon and end up with both vmxon=false and smm.vmxon=false, but all other nVMX state allocated.
