Description

In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]net: libwx: properly reset Rx ring descriptor[EOL][EOL]When device reset is triggered by feature changes such as toggling Rx[EOL]VLAN offload, wx->do_reset() is called to reinitialize Rx rings. The[EOL]hardware descriptor ring may retain stale values from previous sessions.[EOL]And only set the length to 0 in rx_desc[0] would result in building[EOL]malformed SKBs. Fix it to ensure a clean slate after device reset.[EOL][EOL][  549.186435] [     C16] ------------[ cut here ]------------[EOL][  549.186457] [     C16] kernel BUG at net/core/skbuff.c:2814![EOL][  549.186468] [     C16] Oops: invalid opcode: 0000 [#1] SMP NOPTI[EOL][  549.186472] [     C16] CPU: 16 UID: 0 PID: 0 Comm: swapper/16 Kdump: loaded Not tainted 6.16.0-rc4+ #23 PREEMPT(voluntary)[EOL][  549.186476] [     C16] Hardware name: Micro-Star International Co., Ltd.
