Description OSIDB Bzimport 2026-05-27 15:06:27 UTC 
In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Fix memory leak in amdxdna_ubuf_map

The amdxdna_ubuf_map() function allocates memory for sg and
internal sg table structures, but it fails to free them if subsequent
operations (sg_alloc_table_from_pages or dma_map_sgtable) fail.
