Description

In the Linux kernel, the following vulnerability has been resolved: x86/bpf: Fix IP after emitting call depth accounting Adjust the IP passed to `emit_patch` so it calculates the correct offset for the CALL instruction if `x86_call_depth_emit_accounting` emits code. Otherwise we will skip some instructions and most likely crash.

Affected products

• Linux kernel: from 6.2 before 6.6.26; from 6.7 before 6.8.5; 6.9-rc1, 6.9-rc2 — fixed in 6.6.26, 6.8.5

How to fix

Upgrade to a fixed version: Linux kernel 6.6.26, 6.8.5. Check the vendor advisory for mitigations.
