Description
A vulnerability in the Linux kernel's BPF subsystem involving resilient lock operations in rbtree callbacks has been fixed. The issue allowed a comparison callback to release a root lock prematurely, potentially causing use-after-free conditions during tree walks. The fix rejects resilient lock kfuncs in rbtree comparison callbacks to prevent this unsafe behavior.
