UBUNTU-CVE-2024-26883

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix stackmap overflow check on 32-bit arches The stackmap 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 arche...

CVE-2024-26883

CVE-2024-26883 : In the Linux kernel, a vulnerability was fixed that affects 32-bit architectures in the stackmap handling used by BPF. The overflow risk arises when roundup_pow_of_two() is used to compute the number of hash buckets, as a 32‑bit left shift can overflow and cause undefined behavio...

kernel: eBPF multiplication integer overflow in prealloc_elems_and_freelist() in kernel/bpf/stackmap.c leads to out-of-bounds write

An out-of-bounds OOB memory write flaw was found in preallocelemsandfreelist in kernel/bpf/stackmap.c in the bpf in the Linux kernel. In this flaw, the multiplication to calculate the size could lead to an integer overflow which could allow a local attacker, with a special user privilege, to gain...

Medium: kernel

Issue Overview: A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to cause a denial of service. This vulnerability is similar with the older CVE-2019-18808. The highest threat from this vulnerability is to system availability. CVE-2021-3744 A...
