Linux Distros Unpatched Vulnerability : CVE-2025-68237
high Nessus Plugin ID 278822
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- mtdchar: fix integer overflow in read/write ioctls The req.start and req.len variables are u64 values that come from the user at the start of the function. We mask away the high 32 bits of req.len so that's capped at U32_MAX but the req.start variable can go up to U64_MAX which means that the addition can still integer overflow. Use check_add_overflow() to fix this bug. (CVE-2025-68237)
Note that Nessus relies on the presence of the package as reported by the vendor.
