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

tee: optee: Fix kernel panic caused by incorrect error handling

The error path while failing to register devices on the TEE bus has a bug leading to kernel panic as follows:

[ 15.398930] Unable to handle kernel paging request at virtual address ffff07ed00626d7c [ 15.406913] Mem abort info: [ 15.409722] ESR = 0x0000000096000005 [ 15.413490] EC = 0x25: DABT (current EL), IL = 32 bits [ 15.418814] SET = 0, FnV = 0 [ 15.421878] EA = 0, S1PTW = 0 [ 15.425031] FSC = 0x05: level 1 translation fault [ 15.429922] Data abort info: [ 15.432813] ISV = 0, ISS = 0x00000005, ISS2 = 0x00000000 [ 15.438310] CM = 0, WnR = 0, TnD = 0, TagAccess = 0 [ 15.443372] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 [ 15.448697] swapper pgtable: 4k pages, 48-bit VAs, pgdp=00000000d9e3e000 [ 15.455413] [ffff07ed00626d7c] pgd=1800000bffdf9003, p4d=1800000bffdf9003, pud=0000000000000000 [ 15.464146] Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP

Commit 7269cba53d90 ("tee: optee: Fix supplicant based device enumeration") lead to the introduction of this bug. So fix it appropriately.
