CVE-2024-35878: Linux Kernel

Medium severity, CVSS 5.3. EPSS: 0.8% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: of: module: prevent NULL pointer dereference in vsnprintf() In of_modalias(), we can get passed the str and len parameters which would cause a kernel oops in vsnprintf() since it only allows passing a NULL ptr when the length is also 0. Also, we need to filter out the negative values of the len parameter as these will result in a really huge buffer since snprintf() takes size_t parameter while ours is ssize_t... Found by Linux Verification Center (linuxtesting.org) with the Svace static analysis tool.

Affected products

• Linux Linux Kernel: before 6.6.26 (fixed in 6.6.26); from 6.7, before 6.8.5 (fixed in 6.8.5); version 6.9 only
