In the Linux kernel, the following vulnerability has been resolved: bpf: avoid holding freezemutex during mmap operation We use map-freezemutex to prevent races between mapfreeze and memory mapping BPF map contents with writable permissions. The way we naively do this means we'll hold freezemutex...

Improper Authorization in Keycloak Organization Mapper Allows Unauthorized Organization Claims

This vulnerability is caused by the improper mapping of users to organizations based solely on email/username patterns. The issue is limited to the token claim level, meaning the user is not truly added to the organization but may appear as such in applications relying on these claims. The risk...
