Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: perf/core: Added RCU read lock protection to perfiteratectx The perfiteratectx function performs RCU list traversal, but currently lacks RCU read lock protection. This causes lockdep warnings when running perf probes with unshare...

kernel: ndisc: use RCU protection in ndisc_alloc_skb()

A vulnerability was found in the Linux kernel's IPv6 Neighbor Discovery NDISC subsystem, which manages network neighbor information. The issue arises from improper synchronization mechanisms when allocating socket buffers skbuff in the ndiscallocskb function. Specifically, the function can be...
