No CISA KEV listing or public exploit identified at time of analysis, though the issue was discovered via syzkaller fuzzing, demonstrating automated exploit development potential.

This vulnerability is a memory leak in the Linux kernel's AF_XDP socket implementation where buffers fail to be properly returned to the free list due to improper list node reinitialization. The vulnerability affects all Linux kernel versions with the AF_XDP subsystem enabled, potentially allowing local attackers or unprivileged users to exhaust kernel memory over time. While not actively exploited in the wild according to available intelligence, the vulnerability has clear patches available in stable kernel branches and represents a real denial-of-service risk for systems relying on XDP functionality.

The Apple Silicon SMC hwmon driver (macsmc-hwmon) in the Linux kernel contains critical memory safety bugs in sensor population and float conversion logic. Specifically, voltage sensors are incorrectly registered to the temperature sensor array, and float-to-32-bit conversion has flawed exponent handling, potentially leading to out-of-bounds memory access, data corruption, or incorrect fan control on affected Apple Silicon systems. The vulnerability affects Linux kernel versions with the macsmc-hwmon driver and has been patched; no active exploitation or POC is currently known, but the nature of the bugs suggests high real-world risk for systems relying on thermal management.

A use-after-free and list corruption vulnerability exists in the Linux kernel's IPMI (Intelligent Platform Management Interface) subsystem when the SMI sender returns an error. The vulnerability affects all Linux kernel versions with the vulnerable IPMI code path, allowing local attackers or processes with IPMI access to trigger denial of service conditions through list corruption and NULL pointer dereferences. The vulnerability is not currently listed in CISA's KEV catalog, and no CVSS or EPSS scores have been published; however, the technical nature indicates high reliability for exploitation by local actors with kernel interface access.
