漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:firmware: arm_scmi: Fix double free in SMC transport cleanup pathWhen the generic SCMI code tears down a channel, it calls the chan_freecallback function, defined by each transport. Since multiple protocolsmight share the same transport_info member, chan_free() might want toclean up the same member multiple times within the given SCMI transportimplementation. In this case, it is SMC transport. This will lead to a NULLpointer dereference at the second time: | scmi_protocol scmi_dev.1: Enabled polling mode TX channel - prot_id:16 | arm-scmi firmware:scmi: SCMI Notifications - Core Enabled. | arm-scmi firmware:scmi: unable to communicate with SCMI | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 | Mem abort info: | ESR = 0x0000000096000004 | EC = 0x25: DABT (current EL), IL = 32 bits | SET = 0, FnV = 0 | EA = 0, S1PTW = 0 | FSC = 0x04: level 0 translation fault | Data abort info: | ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000 | CM = 0, WnR = 0, TnD = 0, TagAccess = 0 | GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 | user pgtable: 4k pages, 48-bit VAs, pgdp=0000000881ef8000 | [0000000000000000] pgd=0000000000000000, p4d=0000000000000000 | Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP | Modules linked in: | CPU: 4 PID: 1 Comm: swapper/0 Not tainted 6.7.0-rc2-00124-g455ef3d016c9-dirty #793 | Hardware name: FVP Base RevC (DT) | pstate: 61400009 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--) | pc : smc_chan_free+0x3c/0x6c | lr : smc_chan_free+0x3c/0x6c | Call trace: | smc_chan_free+0x3c/0x6c | idr_for_each+0x68/0xf8 | scmi_cleanup_channels.isra.0+0x2c/0x58 | scmi_probe+0x434/0x734 | platform_probe+0x68/0xd8 | really_probe+0x110/0x27c | __driver_probe_device+0x78/0x12c | driver_probe_device+0x3c/0x118 | __driver_attach+0x74/0x128 | bus_for_each_dev+0x78/0xe0 | driver_attach+0x24/0x30 | bus_add_driver+0xe4/0x1e8 | driver_register+0x60/0x128 | __platform_driver_register+0x28/0x34 | scmi_driver_init+0x84/0xc0 | do_one_initcall+0x78/0x33c | kernel_init_freeable+0x2b8/0x51c | kernel_init+0x24/0x130 | ret_from_fork+0x10/0x20 | Code: f0004701 910a0021 aa1403e5 97b91c70 (b9400280) | ---[ end trace 0000000000000000 ]---Simply check for the struct pointer being NULL before trying to accessits members, to avoid this situation.This was found when a transport doesn t really work (for instance no SMCservice), the probe routines then tries to clean up, and triggers a crash.

CVE-2024-26893

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

firmware: arm_scmi: Fix double free in SMC transport cleanup path

When the generic SCMI code tears down a channel, it calls the chan_free
callback function, defined by each transport. Since multiple protocols
might share the same transport_info member, chan_free() might want to
clean up the same member multiple times within the given SCMI transport
implementation. In this case, it is SMC transport. This will lead to a NULL
pointer dereference at the second time:

| arm-scmi firmware:scmi: SCMI Notifications - Core Enabled.

Simply check for the struct pointer being NULL before trying to access
its members, to avoid this situation.

This was found when a transport doesn_x27;t really work (for instance no SMC
service), the probe routines then tries to clean up, and triggers a crash.

状态	需分析	内容
已分析	1.影响性分析说明	In the Linux kernel, the following vulnerability has been resolved:firmware: arm_scmi: Fix double free in SMC transport cleanup pathWhen the generic SCMI code tears down a channel, it calls the chan_freecallback function, defined by each transport. Since multiple protocolsmight share the same transport_info member, chan_free() might want toclean up the same member multiple times within the given SCMI transportimplementation. In this case, it is SMC transport. This will lead to a NULLpointer dereference at the second time:
