In the Linux kernel, the following vulnerability has been resolved:
bonding: fix NULL deref in bond_rr_gen_slave_id
Fix a NULL dereference of the struct bonding.rr_tx_counter member because
if a bond is initially created with an initial mode != zero (Round Robin)
the memory required for the counter is never created and when the mode is
changed there is never any attempt to verify the memory is allocated upon
switching modes.
This causes the following Oops on an aarch64 machine:

In the Linux kernel, the following vulnerability has been resolved:
netfilter: ebtables: fix memory leak when blob is malformed
The bug fix was incomplete, it "replaced" crash with a memory leak.
The old code had an assignment to "ret" embedded into the conditional,
restore this.

ASoC: SOF: Add some bounds checking to firmware data
Smatch complains about "head->full_size - head->header_size" can
underflow. To some extent, we're always going to have to trust the
firmware a bit. However, it's easy enough to add a check for negatives,
and let's add a upper bounds check as well.

An issue was discovered in Logpoint before 7.1.1. Template injection was seen in the search template. The search template uses jinja templating for generating dynamic data. This could be abused to achieve code execution. Any user with access to create a search template can leverage this to execute code as the loginspect user.
