glibc: glibc: Heap Buffer Overflow in `scanf` with `%mc` format specifier and large width
A flaw was found in glibc GNU C Library. This vulnerability occurs when an application uses the scanf family of functions with a %mc format specifier, which is used for dynamically allocating memory for character input, and provides an explicit width greater than 1024. This specific combination c...

EUVD-2026-23978
Calling the scanf family of functions with a %mc malloc'd character match in the GNU C Library version 2.7 to version 2.43 with a format width specifier with an explicit width greater than 1024 could result in a one byte heap buffer overflow...
CVE-2026-5450
CVE-2026-5450 affects the GNU C Library (glibc) where using the scanf family with a %mc format specifier and an explicit width greater than 1024 can trigger a one-byte heap buffer overflow in glibc versions 2.7 through 2.43. Exploitation details are not provided in the sources. Red Hat notes that...
