CVE-2025-23158 | media: venus: hfi: add check to handle incorrect queue size

In the Linux kernel, the following vulnerability has been resolved: media: venus: hfi: add check to handle incorrect queue size qsize represents size of shared queued between driver and video firmware. Firmware can modify this value to an invalid large value. In such situation, empty_space will be bigger than the space actually available. Since new_wr_idx is not checked, so the following code will result in an OOB write. ... qsize = qhdr->q_size if (wr_idx >= rd_idx) empty_space = qsize - (wr_idx - rd_idx) .... if (new_wr_idx < qsize) { memcpy(wr_ptr, packet, dwords << 2) --> OOB write Add check to ensure qsize is within the allocated size while reading and writing packets into the queue.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
7.8 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
