Description OSIDB Bzimport 2025-05-01 14:02:16 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: venus: hfi: add a check to handle OOB in sfr region

sfr->buf_size is in shared memory and can be modified by malicious user.
OOB write is possible when the size is made higher than actual sfr data
buffer. Cap the size to allocated size for such cases.
