Linux: Out-of-bounds Read
CVE-2025-38292 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 920c2db46ca4476c25ec52758441e2e7ab498b0f, 371b340affa52f280f6eadfd25fbd43f09f0d5c0, 5f09d16cd57764c95c8548fe5b70672c9ac01127 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 0.27% 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 920c2db46ca4476c25ec52758441e2e7ab498b0f or 371b340affa52f280f6eadfd25fbd43f09f0d5c0 or 5f09d16cd57764c95c8548fe5b70672c9ac01127 or 9f17747fbda6fca934854463873c4abf8061491d, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.12.34 or 6.15.3, whichever matches your release line, or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix invalid access to memory In ath12k_dp_rx_msdu_coalesce(), rxcb is fetched from skb and boolean is_continuation is part of rxcb. Currently, after freeing the skb, the rxcb->is_continuation accessed again which is wrong since the memory is already freed. This might lead use-after-free error. Hence, fix by locally defining bool is_continuation from rxcb, so that after freeing skb, is_continuation can be used. Compile tested only.

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
- Use a language that provides appropriate memory abstractions.
