Summary
ath11k: disable spectral scan during spectral deinit
Details

In the Linux kernel, the following vulnerability has been resolved:

ath11k: disable spectral scan during spectral deinit

When ath11k modules are removed using rmmod with spectral scan enabled, crash is observed. Different crash trace is observed for each crash.

Send spectral scan disable WMI command to firmware before cleaning the spectral dbring in the spectral_deinit API to avoid this crash.

call trace from one of the crash observed: [ 1252.880802] Unable to handle kernel NULL pointer dereference at virtual address 00000008 [ 1252.882722] pgd = 0f42e886 [ 1252.890955] [00000008] *pgd=00000000 [ 1252.893478] Internal error: Oops: 5 [#1] PREEMPT SMP ARM [ 1253.093035] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.4.89 #0 [ 1253.115261] Hardware name: Generic DT based system [ 1253.121149] PC is at ath11kspectralprocessdata+0x434/0x574 [ath11k] [ 1253.125940] LR is at 0x88e31017 [ 1253.132448] pc : [<7f9387b8>] lr : [<88e31017>] psr: a0000193 [ 1253.135488] sp : 80d01bc8 ip : 00000001 fp : 970e0000 [ 1253.141737] r10: 88e31000 r9 : 970ec000 r8 : 00000080 [ 1253.146946] r7 : 94734040 r6 : a0000113 r5 : 00000057 r4 : 00000000 [ 1253.152159] r3 : e18cb694 r2 : 00000217 r1 : 1df1f000 r0 : 00000001 [ 1253.158755] Flags: NzCv IRQs off FIQs on Mode SVC32 ISA ARM Segment user [ 1253.165266] Control: 10c0383d Table: 5e71006a DAC: 00000055 [ 1253.172472] Process swapper/0 (pid: 0, stack limit = 0x60870141) [ 1253.458055] [<7f9387b8>] (ath11kspectralprocessdata [ath11k]) from [<7f917fdc>] (ath11kdbringbufferreleaseevent+0x214/0x2e4 [ath11k]) [ 1253.466139] [<7f917fdc>] (ath11kdbringbufferreleaseevent [ath11k]) from [<7f8ea3c4>] (ath11kwmitlvoprx+0x1840/0x29cc [ath11k]) [ 1253.478807] [<7f8ea3c4>] (ath11kwmitlvoprx [ath11k]) from [<7f8fe868>] (ath11khtcrxcompletionhandler+0x180/0x4e0 [ath11k]) [ 1253.490699] [<7f8fe868>] (ath11khtcrxcompletionhandler [ath11k]) from [<7f91308c>] (ath11kceperengineservice+0x2c4/0x3b4 [ath11k]) [ 1253.502386] [<7f91308c>] (ath11kceperengineservice [ath11k]) from [<7f9a4198>] (ath11kpcicetasklet+0x28/0x80 [ath11kpci]) [ 1253.514811] [<7f9a4198>] (ath11kpcicetasklet [ath11kpci]) from [<8032227c>] (taskletactioncommon.constprop.2+0x64/0xe8) [ 1253.526476] [<8032227c>] (taskletactioncommon.constprop.2) from [<803021e8>] (dosoftirq+0x130/0x2d0) [ 1253.537756] [<803021e8>] (dosoftirq) from [<80322610>] (irqexit+0xcc/0xe8) [ 1253.547304] [<80322610>] (irqexit) from [<8036a4a4>] (handledomainirq+0x60/0xb4) [ 1253.554428] [<8036a4a4>] (handledomainirq) from [<805eb348>] (gichandleirq+0x4c/0x90) [ 1253.562321] [<805eb348>] (gichandleirq) from [<80301a78>] (irqsvc+0x58/0x8c)
