CVE-2021-47071: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: uio_hv_generic: Fix a memory leak in error handling paths If 'vmbus_establish_gpadl()' fails, the (recv|send)_gpadl will not be updated and 'hv_uio_cleanup()' in the error handling path will not be able to free the corresponding buffer. In such a case, we need to free the buffer explicitly.

Affected products

• Linux Linux Kernel: from 4.20, before 5.4.122 (fixed in 5.4.122); from 5.5, before 5.10.40 (fixed in 5.10.40); from 5.11, before 5.12.7 (fixed in 5.12.7); version 5.13 only
