• RHEL 8.10 Release Notes - Known Issues - Networking

Outdated third-party modules which use the negative_advice() function can crash the kernel
The core networking operation negative_advice() calls the inline dst_negative_advice() and __dst_negative_advice() functions. The kernel in RHEL 8.10 patched a security issue (CVE-2024-36971) in these inline functions. If a third-party module was compiled before the fix, this module might call negative_advice() incorrectly. Consequently, the third-party module can crash the kernel. To solve this problem, use an updated module that correctly calls the negative_advice() function.
