Description Alex 2022-09-01 11:11:59 UTC 
An issue was discovered in the Linux kernel through 5.16-rc6. There is a lack of check after calling vzalloc() and lack of free after
allocation in drivers/media/test-drivers/vidtv/vidtv_s302m.c.

Comment 1 Alex 2022-09-01 11:12:33 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2123312]
Comment 3 Salvatore Bonaccorso 2022-09-02 04:59:10 UTC 
Is the fixed version information correct? The fixing commit seems to be in 5.18-rc1 (and was backported to 5.17.2, 5.16.19, 5.15.33 and 5.10.110).
Comment 4 Alex 2022-09-04 11:28:06 UTC 
Thank you, updated to the Linux kernel 5.18-rc1.
Comment 5 Justin M. Forbes 2022-09-20 14:10:39 UTC 
These drivers were not enabled for Fedora, but for users building their own kernels, it was fixed in the 5.16.19 stable updates source tree.
