kernel: Linux kernel: Use-after-free in BPF sockmap can lead to denial of service and privilege escalation

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap subsystem. A race condition exists where the sksocket is not properly locked or referenced during the skbsendsock function call, allowing for a use-after-free vulnerability. This can be exploited by a local attacker, leadin...

The vulnerability of the bpf_int_jit_compile() function in the arch/arm64/net/bpf_jit_comp.c module, which is part of the networking support on the ARM 64-bit kernel of the Linux operating system, allows a hacker to cause a service failure.

The vulnerability of the bpfintjitcompile function in the arch/arm64/net/bpfjitcomp.c module, which is part of the networking support on the ARM 64-bit Linux operating system, involves executing operations beyond the buffer boundaries in memory.
