NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc-langpack-cmn package and not the glibc-langpack-cmn package as distributed by Amazon-Linux.

The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c.
