In the Linux kernel, the following vulnerability has been resolved:
drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error
Ensure index in rtl2830_pid_filter does not exceed 31 to prevent
out-of-bounds access.
dev->filters is a 32-bit value, so set_bit and clear_bit functions should
only operate on indices from 0 to 31. If index is 32, it will attempt to
access a non-existent 33rd bit, leading to out-of-bounds access.
Change the boundary check from index > 32 to index >= 32 to resolve this
issue.

syzbot reported that nf_reject_ip6_tcphdr_put() was possibly sending
garbage on the four reserved tcp bits (th->res1)

as done in nf_reject_ip_tcphdr_put()

In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Correct the defined value for AMDGPU_DMUB_NOTIFICATION_MAX
[Why & How]
It actually exposes '6' types in enum dmub_notification_type. Not 5. Using smaller
number to create array dmub_callback & dmub_thread_offload has potential to access
item out of array bound. Fix it.

NLnet Labs Unbound up to and including version 1.21.0 contains a vulnerability when handling replies with very large RRsets that it needs to perform name compression for. Malicious upstreams responses with very large RRsets can cause Unbound to spend a considerable time applying name compression to downstream replies. This can lead to degraded performance and eventually denial of service in well orchestrated attacks. The vulnerability can be exploited by a malicious actor querying Unbound for the specially crafted contents of a malicious zone with very large RRsets. Before Unbound replies to the query it will try to apply name compression which was an unbounded operation that could lock the CPU until the whole packet was complete. Unbound version 1.21.1 introduces a hard limit on the number of name compression calculations it is willing to do per packet. Packets that need more compression will result in semi-compressed packets or truncated packets, even on TCP for huge messages, to avoid locking the CPU for long. This change should not affect normal DNS traffic.

In the Linux kernel, the following vulnerability has been resolved:
platform/x86: panasonic-laptop: Fix SINF array out of bounds accesses
The panasonic laptop code in various places uses the SINF array with index
values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array
is big enough.
Not all panasonic laptops have this many SINF array entries, for example
the Toughbook CF-18 model only has 10 SINF array entries. So it only
supports the AC+DC brightness entries and mute.
Check that the SINF array has a minimum size which covers all AC+DC
brightness entries and refuse to load if the SINF array is smaller.
For higher SINF indexes hide the sysfs attributes when the SINF array
does not contain an entry for that attribute, avoiding show()/store()
accessing the array out of bounds and add bounds checking to the probe()
and resume() code accessing these.

Buffer 'card->dai_link' is reallocated in 'meson_card_reallocate_links()',
