Description OSIDB Bzimport 2026-09-11 22:58:50 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: brcmfmac: Fix memory leak in brcmf_sdio_read_control()

The memory allocated for buf is not freed in some of the error paths in
brcmf_sdio_read_control(). Fix that by adding vfree() calls.

[arend: rework as suggested by Johannes]
