Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 6.12.25/6.14.4/6.15-rc3. Affected is the function test_progs of the component riscv. The manipulation with an unknown input leads to a random values vulnerability. CWE is classifying the issue as CWE-330. The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. This is going to have an impact on confidentiality. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: riscv: uprobes: Add missing fence.i after building the XOL buffer The XOL (execute out-of-line) buffer is used to single-step the replaced instruction(s) for uprobes. The RISC-V port was missing a proper fence.i (i$ flushing) after constructing the XOL buffer, which can result in incorrect execution of stale/broken instructions. This was found running the BPF selftests "test_progs: uprobe_autoattach, attach_probe" on the Spacemit K1/X60, where the uprobes tests randomly blew up.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2025-37822 since 04/16/2025. The exploitability is told to be difficult. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1600.001.
