Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: A BTI error was fixed when returning to the patched function. When BPFTRAMPFCALLORIG is set, the BPF trampoline uses BLR to jump back to the instruction next to the call site, in order to call the patched function. Fo...

kernel: bpf, arm64: Fixed a BTI error on returning to patched function

A control-flow integrity flaw was found in the Linux kernel on the arm64 architecture within the extended Berkeley Packet Filter trampoline return path. Returning to a patched function with an instruction sequence that fails the branch-target security check can trigger an exception and panic. A...
