Linux Kernel bpf_xdp_link_attach Heap Buffer Overflow DoS

The vulnerability of the bpfxdplinkattach function in the net/core/dev.c module, which supports networking functions of the Linux kernel, is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity,...

kernel: bpf: Fix use-after-free in bpf_uprobe_multi_link_attach()

A flaw was found in the Linux kernel's extended Berkeley Packet Filter eBPF subsystem. A privileged local attacker, with CAPSYSADMIN capabilities or root access, could exploit a use-after-free vulnerability in the bpfuprobemultilinkattach function. This issue arises when bpflinkprime fails, leadi...
