Linux: Out-of-bounds Read
CVE-2025-37975 is a high-severity out-of-bounds read vulnerability in Linux, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions a068ea00009d373d825c528f9c168501519211b4, 95e4e1c1cf614d125f159db9726b7abb32e18385, 0b4cce68efb93e31a8e51795d696df6e379cb41c as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.19% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Linux to a068ea00009d373d825c528f9c168501519211b4 or 95e4e1c1cf614d125f159db9726b7abb32e18385 or 0b4cce68efb93e31a8e51795d696df6e379cb41c, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.12.25 or 6.14.4, whichever matches your release line, or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: riscv: module: Fix out-of-bounds relocation access The current code allows rel[j] to access one element past the end of the relocation section. Simplify to num_relocations which is equivalent to the existing size expression.
