| In OpenBSD 7.4 before errata 009, a race condition between pf(4)'s processing of packets and expiration of packet states may cause a kernel panic.
|
| A security vulnerability has been detected in appneta tcpreplay 4.5.1. Impacted is the function calc_sleep_time of the file send_packets.c. Such manipulation leads to divide by zero. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. Upgrading to version 4.5.3-beta3 is recommended to address this issue. It is advisable to upgrade the affected component. The vendor confirms in a GitHub issue reply: "Was able to reproduce in 6fcbf03 but NOT 4.5.3-beta3." |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_inner: incorrect percpu area handling under softirq
Softirq can interrupt ongoing packet from process context that is
walking over the percpu area that contains inner header offsets.
Disable bh and perform three checks before restoring the percpu inner
header offsets to validate that the percpu area is valid for this
skbuff:
1) If the NFT_PKTINFO_INNER_FULL flag is set on, then this skbuff
has already been parsed before for inner header fetching to
register.
2) Validate that the percpu area refers to this skbuff using the
skbuff pointer as a cookie. If there is a cookie mismatch, then
this skbuff needs to be parsed again.
3) Finally, validate if the percpu area refers to this tunnel type.
Only after these three checks the percpu area is restored to a on-stack
copy and bh is enabled again.
After inner header fetching, the on-stack copy is stored back to the
percpu area. |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Versions between 2.1.0 and 2.14.19, 3.2.0-rc1, 3.1.0-rc1 through 3.1.7, and 3.0.0-rc1 through 3.0.18 contain a race condition in the repository credentials handler that can cause the Argo CD server to panic and crash when concurrent operations are performed on the same repository URL. The vulnerability is located in numerous repository related handlers in the util/db/repository_secrets.go file. A valid API token with repositories resource permissions (create, update, or delete actions) is required to trigger the race condition. This vulnerability causes the entire Argo CD server to crash and become unavailable. Attackers can repeatedly and continuously trigger the race condition to maintain a denial-of-service state, disrupting all GitOps operations. This issue is fixed in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19. |

Workqueue: events_unbound kfree_rcu_monitor
<snip>
kfree_rcu_monitor() rearms the work if a "krcp" has to be still
offloaded and this is done without holding krcp->lock, whereas
the kvfree_call_rcu() holds it.
Fix it by acquiring the "krcp->lock" for kfree_rcu_monitor() so
both functions do not race anymore. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix race condition between reset and nvme_dev_disable()
nvme_dev_disable() modifies the dev->online_queues field, therefore
nvme_pci_update_nr_queues() should avoid racing against it, otherwise
we could end up passing invalid values to blk_mq_update_nr_hw_queues().

| In the Linux kernel, the following vulnerability has been resolved:
spi: sn-f-ospi: Fix division by zero
When there is no dummy cycle in the spi-nor commands, both dummy bus cycle
bytes and width are zero. Because of the cpu's warning when divided by
zero, the warning should be avoided. Return just zero to avoid such
calculations. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Initialize denominator defaults to 1
[WHAT & HOW]
Variables, used as denominators and maybe not assigned to other values,
should be initialized to non-zero to avoid DIVIDE_BY_ZERO, as reported
by Coverity.
(cherry picked from commit e2c4c6c10542ccfe4a0830bb6c9fd5b177b7bbb7) |
| In the Linux kernel, the following vulnerability has been resolved:
fgraph: Add READ_ONCE() when accessing fgraph_array[]
In __ftrace_return_to_handler(), a loop iterates over the fgraph_array[]
elements, which are fgraph_ops. The loop checks if an element is a
fgraph_stub to prevent using a fgraph_stub afterward.
However, if the compiler reloads fgraph_array[] after this check, it might
race with an update to fgraph_array[] that introduces a fgraph_stub. This
could result in the stub being processed, but the stub contains a null
"func_hash" field, leading to a NULL pointer dereference.
To ensure that the gops compared against the fgraph_stub matches the gops
processed later, add a READ_ONCE(). A similar patch appears in commit
63a8dfb ("function_graph: Add READ_ONCE() when accessing fgraph_array[]"). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix divide error in DM plane scale calcs
dm_get_plane_scale doesn't take into account plane scaled size equal to
zero, leading to a kernel oops due to division by zero. Fix by setting
out-scale size as zero when the dst size is zero, similar to what is
done by drm_calc_scale(). This issue started with the introduction of
cursor ovelay mode that uses this function to assess cursor mode changes
via dm_crtc_get_cursor_mode() before checking plane state.
