CVE-2024-35969

Summary (CVE-2024-35969): A race in IPv6 handling in the Linux kernel between ipv6_get_ifaddr and ipv6_del_addr can cause use-after-free scenarios. When an entry is removed from inet6_addr_lst under RCU, ipv6_get_ifaddr may still return that entry and attempt to increment its reference, leading t...

CVE-2022-48687

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix out-of-bounds read when setting HMAC data. The SRv6 layer allows defining HMAC data that can later be used to sign IPv6 Segment Routing Headers. This configuration is realised via netlink through four attributes:...
