CVE-2024-38594

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: stmmac: move the EST lock to struct stmmac_priv<br /> <br /> Reinitialize the whole EST structure would also reset the mutex<br /> lock which is embedded in the EST structure, and then trigger<br /> the following warning. To address this, move the lock to struct<br /> stmmac_priv. We also need to reacquire the mutex lock when doing<br /> this initialization.<br /> <br /> DEBUG_LOCKS_WARN_ON(lock-&gt;magic != lock)<br /> WARNING: CPU: 3 PID: 505 at kernel/locking/mutex.c:587 __mutex_lock+0xd84/0x1068<br /> Modules linked in:<br /> CPU: 3 PID: 505 Comm: tc Not tainted 6.9.0-rc6-00053-g0106679839f7-dirty #29<br /> Hardware name: NXP i.MX8MPlus EVK board (DT)<br /> pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)<br /> pc : __mutex_lock+0xd84/0x1068<br /> lr : __mutex_lock+0xd84/0x1068<br /> sp : ffffffc0864e3570<br /> x29: ffffffc0864e3570 x28: ffffffc0817bdc78 x27: 0000000000000003<br /> x26: ffffff80c54f1808 x25: ffffff80c9164080 x24: ffffffc080d723ac<br /> x23: 0000000000000000 x22: 0000000000000002 x21: 0000000000000000<br /> x20: 0000000000000000 x19: ffffffc083bc3000 x18: ffffffffffffffff<br /> x17: ffffffc08117b080 x16: 0000000000000002 x15: ffffff80d2d40000<br /> x14: 00000000000002da x13: ffffff80d2d404b8 x12: ffffffc082b5a5c8<br /> x11: ffffffc082bca680 x10: ffffffc082bb2640 x9 : ffffffc082bb2698<br /> x8 : 0000000000017fe8 x7 : c0000000ffffefff x6 : 0000000000000001<br /> x5 : ffffff8178fe0d48 x4 : 0000000000000000 x3 : 0000000000000027<br /> x2 : ffffff8178fe0d50 x1 : 0000000000000000 x0 : 0000000000000000<br /> Call trace:<br /> __mutex_lock+0xd84/0x1068<br /> mutex_lock_nested+0x28/0x34<br /> tc_setup_taprio+0x118/0x68c<br /> stmmac_setup_tc+0x50/0xf0<br /> taprio_change+0x868/0xc9c
