CVE-2022-49625: In the Linux kernel, the following vulnerability has been resolved: sfc: fix kernel panic when creating VF When creati
Summary
A bug in the Linux kernel's sfc (Solarflare network driver) caused a kernel panic when creating virtual functions (VFs, which are virtual network devices that share a physical network card). The crash happened because the code tried to unmap memory using vunmap while in an interrupt context, which is not allowed.
Solution / Mitigation
The patch reenables bottom-half processing (BH) before releasing the DMA coherent buffer (a block of memory used for direct memory access between devices). This allows vunmap to safely unmap the memory outside of the interrupt context where it would cause a crash.
