CVE-2026-74495

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak exists in the igbvf driver during TX DMA error cleanup. When an error occurs while mapping TX buffers, the driver fails to correctly unmap all buffers already mapped for the socket buffer (skb). This is caused by an off-by-one error where the count variable is decremented before the while loop in the dma error() function. Consequently, if any mapping was successful prior to the failure, one DMA mapping (the head) is leaked.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
