CVSS 3.1
7.8 highCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2025-21715
High (7.8) in linux linux kernel. EPSS 0.2% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
net: davicom: fix UAF in dm9000_drv_remove
dm is netdev private data and it cannot be
used after free_netdev() call. Using dm after free_netdev()
can cause UAF bug. Fix it by moving free_netdev() at the end of the
function.
This is similar to the issue fixed in commit
ad297cd2db89 ("net: qcom/emac: fix UAF in emac_remove").
This bug is detected by our static analysis tool.
