CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2021-47645
Medium (5.5) in linux linux kernel. EPSS 0.3% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
media: staging: media: zoran: calculate the right buffer number for zoran_reap_stat_com
On the case tmp_dcim=1, the index of buffer is miscalculated.
This generate a NULL pointer dereference later.
So let's fix the calcul and add a check to prevent this to reappear.
