FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect

glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over-read
In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-based buffer over-read via an attempted case-insensitive regular-expression match.
Statement: As per upstream “resource exhaustion issues which can be triggered only with crafted patterns (either during compilation or execution) are not treated as security bugs”. The regular expression compiler in glibc is only supposed to be exposed to trusted content, therefore upstream does not consider this bug as a security vulnerability.
