Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the BPF TCP implementation where a double socket release can occur during batch reallocation. The function bpf iter tcp batch releases the current batch using bpf iter...

The vulnerability of the bpf_iter_bits_new() function in the kernel/bpf/helpers.c module, which supports the BPF interpreter for Linux kernels, allows a hacker to trigger a service failure.

The vulnerability of the bpfiterbitsnew function in the kernel/bpf/helpers.c file, which is part of the BPF interpreter support for Linux kernel, involves integer overflow. Exploiting this vulnerability could allow an attacker to cause a system failure...

kernel: sched_ext: bpf_iter_scx_dsq_new() should always initialize iterator

In the Linux kernel, the following vulnerability has been resolved: schedext: bpfiterscxdsqnew should always initialize iterator BPF programs may call next and destroy on BPF iterators even after new returns an error value e.g. bpfforeach macro ignores error returns from new. bpfiterscxdsqnew cou...
