CVE-2026-46041

CVE-2026-46041 affects the Linux kernel with a fix for sleeping in an atomic context in the hdlc path used by greybus/gb-beagleplay. The root cause is that hdlc_append() calls usleep_range() while tx_producer_lock (a spinlock) is held, risking a BUG: scheduling while atomic. The workaround is to ...
