Timing variability in `curve25519-dalek`'s `Scalar29::sub`/`Scalar52::sub`

Timing variability of any kind is problematic when working with potentially secret values such as elliptic curve scalars, and such issues can potentially leak private keys and other secrets. Such a problem was recently discovered in curve25519-dalek. The Scalar29::sub 32-bit and Scalar52::sub...

kernel: NULL pointer dereference in nvmet_tcp_build_iovec

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing kernel panic and a denial of service...

kernel: NVMe: info leak due to out-of-bounds read in nvmet_ctrl_find_get

An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer...
