Linux: Out-of-bounds Read
CVE-2025-38286 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 264a5cf0c422e65c94447a1ebebfac7c92690670, db5665cbfd766db7d8cd0e5fd6e3c0b412916774, 2ecafe59668d2506a68459a9d169ebe41a147a41 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 0.21% 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 264a5cf0c422e65c94447a1ebebfac7c92690670 or db5665cbfd766db7d8cd0e5fd6e3c0b412916774 or 2ecafe59668d2506a68459a9d169ebe41a147a41 or f1c1fdc41fbf7e308ced9c86f3f66345a3f6f478, whichever matches your release line, or a later version.
- Update Linux Kernel to 5.4.295 or 5.10.239 or 5.15.186 or 6.1.142, whichever matches your release line, or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: pinctrl: at91: Fix possible out-of-boundary access at91_gpio_probe() doesn't check that given OF alias is not available or something went wrong when trying to get it. This might have consequences when accessing gpio_chips array with that value as an index. Note, that BUG() can be compiled out and hence won't actually perform the required checks.

The underlying weakness: Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.
How developers prevent this class of flaw
