Linux: Out-of-bounds Read
CVE-2025-38081 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 7a27d8dd9354f00e823dfb557b690ea44b4a146f, 4a120221661fcecb253448d7b041a52d47f1d91f, ace57bd1fb49d193edec5f6a1f255f48dd5fca90 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 7a27d8dd9354f00e823dfb557b690ea44b4a146f or 4a120221661fcecb253448d7b041a52d47f1d91f or ace57bd1fb49d193edec5f6a1f255f48dd5fca90 or 254e04ec799c1ff8c1e2bd08a57c6a849895d6ff, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.6.93 or 6.12.31 or 6.14.9, whichever matches your release line, or a later version.

How the severity score breaks down
- Attack vector
- LocalThe attacker needs local access or must trick a user into running something.
- Attack complexity
- LowNo special conditions are needed; the attack works reliably.
- Privileges required
- LowA basic user account is enough.
- User interaction

Official description
In the Linux kernel, the following vulnerability has been resolved: spi-rockchip: Fix register out of bounds access Do not write native chip select stuff for GPIO chip selects. GPIOs can be numbered much higher than native CS. Also, it makes no sense.
