-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
An off-by-one bug is found in the x86_64 cond jump target of the BPF JIT filter code. In case a conditional jump is followed by a long jump, conditional jump target is one byte past the start of target instruction. A user/program could use this flaw to crash the kernel resulting in DoS, or potentially escalate user privileges on a system to gain root access. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a03ffcf873fe0f2565386ca8ef832144c42e67fa
