CVE-2024-26952 [HIGH] CWE-120 ksmbd: fix potencial out-of-bounds when buffer offset is invalid
ksmbd: fix potencial out-of-bounds when buffer offset is invalid
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.

CVE-2024-26952 [HIGH] CWE-120 kernel: ksmbd: fix potencial out-of-bounds when buffer offset is invalid
kernel: ksmbd: fix potencial out-of-bounds when buffer offset is invalid
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix potencial out-of-bounds when buffer offset is invalid
I found potencial out-of-bounds when buffer offset fields of a few requests
is invalid. This patch set the minimum value of buffer offset field to
->Buffer offset to validate buffer length.
A flaw was found in the Linux kernel’s ksmbd module. An incorrect validation of a buffer length can trigger an out-of-bounds access, resulting in a denial of service.
Statement: The ksmbd module is not built in the kernel shipped in Red Hat Enterprise Linux, so it is not affected by this vulnerability.
