The vulnerability of the bpf_tail_call_direct_fixup() function in the arch/x86/net/bpf_jit_comp.c module exposes network function support on the Linux kernel-based x86 platform, allowing attackers to cause system failures.

The vulnerability of the bpftailcalldirectfixup function in the arch/x86/net/bpfjitcomp.c module, which supports networking functions on the x86 kernel of the Linux operating system, is related to the reutilization of previously freed memory. Exploiting this vulnerability can allow an attacker to...
