Linux BPF Free Htab Elem Heap Overflow DoS

The vulnerability of the freehtabelem function in the kernel/bpf/hashtab.c module, which is part of the Linux kernel’s BPF support for kernel-level instrumentation, relates to the use of uninitialized variables. Exploiting this vulnerability could allow an attacker to cause a service failure...

Linux kernel BPF Heap Buffer Overflow DoS

The vulnerability of the htabmapalloc function in the kernel/bpf/hashtab.c module of the Linux operating system’s BPF subsystem in 32-bit architectures is related to integer overflow. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

SUSE CVE-2024-26884

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix hashtab overflow check on 32-bit arches The hashtab code relies on rounduppowoftwo to compute the number of hash buckets, and contains an overflow check by checking if the resulting value is 0. However, on 32-bit arches,...
