Description
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: CGX: fix bitmap leaks
The RX/TX flow-control bitmaps (rx_fc_pfvf_bmap and tx_fc_pfvf_bmap)
are allocated by cgx_lmac_init() but never freed in cgx_lmac_exit().
Unbinding and rebinding the driver therefore triggers kmemleak:
unreferenced object (size 16):
backtrace:
rvu_alloc_bitmap
cgx_probe
Free both bitmaps during teardown.
Affected configurations
• linux linux kernel (>= 5.18 < 6.1.165)
• linux linux kernel (>= 6.2 < 6.6.128)
• linux linux kernel (>= 6.7 < 6.12.75)
