Description

In the Linux kernel, the following vulnerability has been resolved:

media: vidtv: fix pass-by-value structs causing MSAN warnings

vidtv_ts_null_write_into() and vidtv_ts_pcr_write_into() take their
argument structs by value, causing MSAN to report uninit-value warnings.
While only vidtv_ts_null_write_into() has triggered a report so far,
both functions share the same issue.

Fix by passing both structs by const pointer instead, avoiding the
stack copy of the struct along with its MSAN shadow and origin metadata.
The functions do not modify the structs, which is enforced by the const
qualifier.

CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/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:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
