CVE-2024-39489: ipv6: sr: fix memleak in seg6_hmac_init_algo

Published Jul 10, 2024

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

ipv6: sr: fix memleak in seg6hmacinitalgo

seg6hmacinitalgo returns without cleaning up the previous allocations if one fails, so it's going to leak all that memory and the crypto tfms.

Update seg6hmacexit to only free the memory when allocated, so we can reuse the code directly.
