CVE-2023-52997

CVE-2023-52997 is a Linux kernel vulnerability affecting ipv4: ip_metrics_convert() where an attacker could exploit speculative execution to leak kernel memory content. The issue arises from using a value as an array index (type) without sufficient protection, allowing a spectre v1 gadget. The de...

Important: kernel

Issue Overview: An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flushtoldisc function. This flaw allows a local user...
