CVE-2023-53184

The CVE-2023-53184 entry concerns a Linux kernel vulnerability in arm64 SME (SVE state handling). The root cause is that the vector length is updated after allocating the SVE state, causing allocation with the old length and potential memory corruption from an undersized buffer. The fix moves the...

CVE-2023-53165

CVE-2023-53165 is a Linux kernel vulnerability in the UDF filesystem code. The issue is an uninitialized array read in the UDF charset conversion when processing filenames that begin with a dot and are 2–5 characters long, which can cause the output name to be prepended with a “unification hash” ...

CVE-2022-50253

CVE-2022-50253 is a Linux kernel issue where bpf code did not ensure skb->len was non-zero when redirecting to a tunneling device, leading to a length underflow/invalid skb handling path after __skb_pull in certain redirect paths. The vulnerability is exploited via BPF/XDP filtering paths that...

kernel: net: usb: smsc75xx: Limit packet length to skb->len

In the Linux kernel, the following vulnerability has been resolved: net: usb: smsc75xx: Limit packet length to skb-len Packet length retrieved from skb data may be larger than the actual socket buffer length up to 9026 bytes. In such case the cloned skb passed up the network stack will leak kerne...
