| In the Linux kernel, the following vulnerability has been resolved:
ipv6/addrconf: fix a potential refcount underflow for idev
Now in addrconf_mod_rs_timer(), reference idev depends on whether
rs_timer is not pending. Then modify rs_timer timeout.
There is a time gap in [1], during which if the pending rs_timer
becomes not pending. It will miss to hold idev, but the rs_timer
is activated. Thus rs_timer callback function addrconf_rs_timer()
will be executed and put idev later without holding idev. A refcount
underflow issue for idev can be caused by this.
if (!timer_pending(&idev->rs_timer))
in6_dev_hold(idev);
<--------------[1]
mod_timer(&idev->rs_timer, jiffies + when);
To fix the issue, hold idev if mod_timer() return 0. |
| In the Linux kernel, the following vulnerability has been resolved:
vxlan: Fix memory leaks in error path
The memory allocated by vxlan_vnigroup_init() is not freed in the error
path, leading to memory leaks [1]. Fix by calling
vxlan_vnigroup_uninit() in the error path.
The leaks can be reproduced by annotating gro_cells_init() with
ALLOW_ERROR_INJECTION() and then running:
# echo "100" > /sys/kernel/debug/fail_function/probability
# echo "1" > /sys/kernel/debug/fail_function/times
# echo "gro_cells_init" > /sys/kernel/debug/fail_function/inject
# printf %#x -12 > /sys/kernel/debug/fail_function/gro_cells_init/retval
# ip link add name vxlan0 type vxlan dstport 4789 external vnifilter

| In the Linux kernel, the following vulnerability has been resolved:
irqchip/alpine-msi: Fix refcount leak in alpine_msix_init_domains
of_irq_find_parent() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
vxlan: Fix nexthop hash size
The nexthop code expects a 31 bit hash, such as what is returned by
fib_multipath_hash() and rt6_multipath_hash(). Passing the 32 bit hash
returned by skb_get_hash() can lead to problems related to the fact that
'int hash' is a negative number when the MSB is set.
In the case of hash threshold nexthop groups, nexthop_select_path_hthr()
will disproportionately select the first nexthop group entry. In the case
of resilient nexthop groups, nexthop_select_path_res() may do an out of
bounds access in nh_buckets[], for example:
hash = -912054133
num_nh_buckets = 2
bucket_index = 65535
which leads to the following panic:

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix amdgpu_irq_put call trace in gmc_v10_0_hw_fini
The gmc.ecc_irq is enabled by firmware per IFWI setting,
and the host driver is not privileged to enable/disable
the interrupt. So, it is meaningless to use the amdgpu_irq_put
function in gmc_v10_0_hw_fini, which also leads to the call
trace.
