Information Exposure Affecting torvalds/linux package, versions [6.11,6.12.77)[6.13,6.18.17)[6.19,6.19.7)
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Information Exposure in the fib_multipath_hash_from_keys process. An attacker can cause a kernel panic or disrupt system stability by triggering an alignment fault through improper access to the sysctl_fib_multipath_hash_seed structure on ARM64 systems when compiled with Clang and LTO enabled. This is only exploitable if the kernel is built for ARM64 architecture with Clang and Link Time Optimization (LTO) enabled.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
