Linux: >> Linux Kernel >> 2.6.16.29 Security Vulnerabilities
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: Update intermediate power state for SI
Update the current state as boot state during dpm initialization.
During the subsequent initialization, set_power_state gets called to
transition to the final power state. set_power_state refers to values
from the current state and without current state populated, it could
result in NULL pointer dereference.
For ex: on platforms where PCI speed change is supported through ACPI
ATCS method, the link speed of current state needs to be queried before
deciding on changing to final power state's link speed. The logic to query
ATCS-support was broken on certain platforms. The issue became visible
when broken ATCS-support logic got fixed with commit
f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

In the Linux kernel, the following vulnerability has been resolved:
RDMA/cma: Fix rdma_resolve_route() memory leak
Fix a memory leak when "mda_resolve_route() is called more than once on
the same "rdma_cm_id".
This is possible if cma_query_handler() triggers the
RDMA_CM_EVENT_ROUTE_ERROR flow which puts the state machine back and
allows rdma_resolve_route() to be called again.

In the Linux kernel, the following vulnerability has been resolved:
wl1251: Fix possible buffer overflow in wl1251_cmd_scan
Function wl1251_cmd_scan calls memcpy without checking the length.
Harden by checking the length is within the maximum allowed size.

In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Avoid HDCP over-read and corruption
Instead of reading the desired 5 bytes of the actual target field,
the code was reading 8. This could result in a corrupted value if the
trailing 3 bytes were non-zero, so instead use an appropriately sized
and zero-initialized bounce buffer, and read only 5 bytes before casting
to u64.

In the Linux kernel, the following vulnerability has been resolved:
virtio-net: Add validation for used length
This adds validation for used length (might come
from an untrusted device) to avoid data corruption
or loss.

In the Linux kernel, the following vulnerability has been resolved:
udf: Fix NULL pointer dereference in udf_symlink function
In function udf_symlink, epos.bh is assigned with the value returned
by udf_tgetblk. The function udf_tgetblk is defined in udf/misc.c
and returns the value of sb_getblk function that could be NULL.
Then, epos.bh is used without any check, causing a possible
NULL pointer dereference when sb_getblk fails.
This fix adds a check to validate the value of epos.bh.

In the Linux kernel, the following vulnerability has been resolved:
atm: nicstar: Fix possible use-after-free in nicstar_cleanup()
This module's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

In the Linux kernel, the following vulnerability has been resolved:
usb: common: usb-conn-gpio: fix NULL pointer dereference of charger
When power on system with OTG cable, IDDIG's interrupt arises before
the charger registration, it will cause a NULL pointer dereference,
fix the issue by registering the power supply before requesting
IDDIG/VBUS irq.
