New CVE-2024-44985 Open this link in a new tabHow to fix?
Upgrade SLES:15.6 kernel-syms to version 6.4.0-150600.23.25.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES.
See How to fix? for SLES:15.6 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
ipv6: prevent possible UAF in ip6_xmit()
If skb_expand_head() returns NULL, skb has been freed and the associated dst/idev could also have been freed.
We must use rcu_read_lock() to prevent a possible UAF.
