Linux: Out-of-bounds Read
CVE-2025-22112 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 e1724f07693439deaa413ebc2a2640325cf247f5, b1e081d331ab3a0dea25425f2b6ddeb365fc9d22, 919f9f497dbcee75d487400e8f9815b74a6a37df 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 e1724f07693439deaa413ebc2a2640325cf247f5 or b1e081d331ab3a0dea25425f2b6ddeb365fc9d22 or 919f9f497dbcee75d487400e8f9815b74a6a37df or 6.12.35, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.12.35 or 6.14, whichever matches your release line, or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: eth: bnxt: fix out-of-range access of vnic_info array The bnxt_queue_{start | stop}() access vnic_info as much as allocated, which indicates bp->nr_vnics. So, it should not reach bp->vnic_info[bp->nr_vnics].
