Summary
In the Linux kernel, the following vulnerability has been resolved: security: Restrict CONFIG_ZERO_CALL_USED_REGS to gcc or clang > 15.0.6 A bad bug in clang's implementation of -fzero-call-used-regs can result in NULL pointer dereferences (see the links above the check for more information). Restrict CONFIG_CC_HAS_ZERO_CALL_USED_REGS to either a supported GCC version or a clang newer than 15.0.6, which will catch both a theoretical 15.0.7 and the upcoming 16.0.0, which will both have the bug fixed.
