CVE-2025-40019 [MEDIUM] CWE-787 kernel: crypto: essiv - Check ssize for decryption and in-place encryption
kernel: crypto: essiv - Check ssize for decryption and in-place encryption
In the Linux kernel, the following vulnerability has been resolved:
crypto: essiv - Check ssize for decryption and in-place encryption
Move the ssize check to the start in essiv_aead_crypt so that
it's also checked for decryption and in-place encryption.
Statement: The ESSIV AEAD path failed to validate ssize = assoclen - ivsize for decryption and in-place encryption. A negative ssize could flow into scatterwalk_map_and_copy(), causing out-of-bounds writes/reads of the IV region and kernel crashes or memory corruption. The fix computes ivsize/ssize up front, rejects ssize < 0, and consistently uses these locals across branches, covering decrypt and in-place cases. Privilege required is local (e.g., reachable via k

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 this.
