CVE-2022-50812: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux: from 5.15, before 5.15.86 (fixed in 5.15.86); from 5.16, before 6.0.16 (fixed in 6.0.16); from 6.1, before 6.1.2 (fixed in 6.1.2)
