Linux: >> Linux Kernel >> 2.6.15.3 Security Vulnerabilities
In the Linux kernel, the following vulnerability has been resolved:
kunit/overflow: Fix UB in overflow_allocation_test
The 'device_name' array doesn't exist out of the
'overflow_allocation_test' function scope. However, it is being used as
a driver name when calling 'kunit_driver_create' from
'kunit_device_register'. It produces the kernel panic with KASAN
enabled.
Since this variable is used in one place only, remove it and pass the
device name into kunit_device_register directly as an ascii string.

In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check debug trap enable before write dbg_ev_file
In interrupt context, write dbg_ev_file will be run by work queue. It
will cause write dbg_ev_file execution after debug_trap_disable, which
will cause NULL pointer access.
v2: cancel work "debug_event_workarea" before set dbg_ev_file as NULL.

In the Linux kernel, the following vulnerability has been resolved:
x86/tdx: Fix data leak in mmio_read()
The mmio_read() function makes a TDVMCALL to retrieve MMIO data for an
address from the VMM.
Sean noticed that mmio_read() unintentionally exposes the value of an
initialized variable (val) on the stack to the VMM.
This variable is only needed as an output value. It did not need to be
passed to the VMM in the first place.
Do not send the original value of *val to the VMM.
[ dhansen: clarify what 'val' is used for. ]
