Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2024-12-31 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

hsr: Prevent use after free in prp_create_tagged_frame()

The prp_fill_rct() function can fail. In that situation, it frees the skb and returns NULL. Meanwhile on the success path, it returns the original skb. So it's straight forward to fix bug by using the returned value.

Severity ?

7.8 (High)
