CVE-2026-98060: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject resilient lock operations in rbtree callbacks bpfrbtreeadd keeps parent and link pointers live across calls to the program-supplied comparison callback. The verifier therefore requires the root's lock to remain held...

ROS-20260925-73-0148

The vulnerability of the BTFID function in the kernel/bpf/verifier.c module, which is part of the BPF interpreter support for Linux’s operating system, is related to an uncontrolled recursion. Exploiting this vulnerability could allow a attacker to cause a service failure...

ROS-20260925-73-0179
