CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2022-49583
Medium (5.5) in linux linux kernel. EPSS 0.3% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix handling of dummy receive descriptors
Fix memory leak caused by not handling dummy receive descriptor properly.
iavf_get_rx_buffer now sets the rx_buffer return value for dummy receive
descriptors. Without this patch, when the hardware writes a dummy
descriptor, iavf would not free the page allocated for the previous receive
buffer. This is an unlikely event but can still happen.
