Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
media: vidtv: fix pass-by-value structs causing MSAN warnings<br />
<br />
vidtv_ts_null_write_into() and vidtv_ts_pcr_write_into() take their<br />
argument structs by value, causing MSAN to report uninit-value warnings.<br />
While only vidtv_ts_null_write_into() has triggered a report so far,<br />
both functions share the same issue.<br />
<br />
Fix by passing both structs by const pointer instead, avoiding the<br />
stack copy of the struct along with its MSAN shadow and origin metadata.<br />
The functions do not modify the structs, which is enforced by the const<br />
qualifier.
Impacto
