CVE-2022-49687 (Moderate severity, published 2025-02-25)
CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
Description: In the Linux kernel, the following vulnerability has been resolved:

virtio_net: fix xdp_rxq_info bug after suspend/resume

The following sequence currently causes a driver bug warning
when using virtio_net:

  # ip link set eth0 up
  # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem)
  <resume>
  # ip link set eth0 down

  Missing register, driver bug
  WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60
  Call trace:

   dev_change_flags+0x24/0x64
   do_setlink+0x230/0xdd0
   ...

This happens because virtnet_freeze() frees the receive_queue
completely (including struct xdp_rxq_info) but does not call
xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the
receive_queue again but does not call xdp_rxq_info_reg().

Actually, parts of virtnet_freeze_down() and virtnet_restore_up()
are almost identical to virtnet_close() and virtnet_open(): only
the calls to xdp_rxq_info_(un)reg() are missing. This means that
we can fix this easily and avoid such problems in the future by
just calling virtnet_close()/open() from the freeze/restore handlers.

Aside from adding the missing xdp_rxq_info calls the only difference
is that the refill work is only cancelled if netif_running(). However,
this should not make any functional difference since the refill work
should only be active if the network interface is actually up.

Description: In the Linux kernel, the following vulnerability has been resolved:

misc: fastrpc: fix list iterator in fastrpc_req_mem_unmap_impl

This is another instance of incorrect use of list iterator and
checking it for NULL.

The list iterator value 'map' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty (in this case, the
check 'if (!map) {' will always be false and never exit as expected).

To fix the bug, use a new variable 'iter' as the list iterator,
while use the original variable 'map' as a dedicated pointer to
point to the found element.

Without this patch, Kernel crashes with below trace:

CWE: CWE-416
Description: A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
CVE-2022-49669 (Important severity, published 2025-02-25)
CVSS score: 7.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
Description: In the Linux kernel, the following vulnerability has been resolved:

mptcp: fix race on unaccepted mptcp sockets

When the listener socket owning the relevant request is closed,
it frees the unaccepted subflows and that causes later deletion
of the paired MPTCP sockets.

The mptcp socket's worker can run in the time interval between such delete
operations. When that happens, any access to msk->first will cause an UaF
access, as the subflow cleanup did not cleared such field in the mptcp
socket.

Address the issue explicitly traversing the listener socket accept
queue at close time and performing the needed cleanup on the pending
msk.

Note that the locking is a bit tricky, as we need to acquire the msk
socket lock, while still owning the subflow socket one.
Statement: No Red Hat products contain the affected code.

Description: In the Linux kernel, the following vulnerability has been resolved:

ALSA: seq: Fix function prototype mismatch in snd_seq_expand_var_event

With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed.

seq_copy_in_user() and seq_copy_in_kernel() did not have prototypes
matching snd_seq_dump_func_t. Adjust this and remove the casts. There
are not resulting binary output differences.

This was found as a result of Clang's new -Wcast-function-type-strict
flag, which is more sensitive than the simpler -Wcast-function-type,
which only checks for type width mismatches.

CWE: CWE-824
Description: A flaw was found in the Linux kernel’s Time-Aware Priority Shaper (taprio) scheduler. The issue arises because the taprio scheduler attempts to disable hardware offload, even if it was never enabled, due to an unusual API design. This issue can result in improper handling and potential system instability.
Statement: The vulnerability has a CVSS v3 score of 6.1, reflecting the potential for local attackers to exploit and impact system availability. However, confidentiality and integrity are less affected by this issue. The vulnerability was resolved by modifying the kernel to ensure offload disabling only occurs when it was actually enabled.

netfilter: conntrack: revisit gc autotuning

as of commit 4608fdfc07e1
("netfilter: conntrack: collect all entries in one cycle")
conntrack gc was changed to run every 2 minutes.

On systems where conntrack hash table is set to large value, most evictions
happen from gc worker rather than the packet path due to hash table
distribution.

This causes netlink event overflows when events are collected.

This change collects average expiry of scanned entries and
reschedules to the average remaining value, within 1 to 60 second interval.

To avoid event overflows, reschedule after each bucket and add a
limit for both run time and number of evictions per run.

If more entries have to be evicted, reschedule and restart 1 jiffy
into the future.

CWE: CWE-401
Description: A flaw was found in damon_sysfs_add_target in mm/damon/sysfs.c within the Netfilter component in the Linux Kernel. This issue may lead to a memory leak problem.
Statement: No shipped kernel versions were seen affected with this problem since these files are not built in our source code.
CVE-2022-4055 (Moderate severity, published 2022-08-02)
CVSS score: 7.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N)
Description: When xdg-mail is configured to use thunderbird for mailto URLs, improper parsing of the URL can lead to additional headers being passed to thunderbird that should not be included per RFC 2368. An attacker can use this method to create a mailto URL that looks safe to users, but will actually attach files when clicked.
Statement: To exploit this flaw, an attacker would need to convince a user to click on a specially crafted mailto URL. Additionally, the user must have the Thunderbird email client installed and xdg-mail configured to use Thunderbird to handle mailto URLs. Therefore, this vulnerability is rated as moderate rather than important because it requires user interaction and specific system configurations.
Mitigation: To mitigate this flaw, either:
1. Do not use mailto links at all
2. Always double-check in the user interface that there are no unwanted attachments before sending emails; especially when the email originates from clicking a mailto link.
CVE-2022-2928 (Moderate severity, published 2022-10-04)
CVSS score: 6.5 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-190
Description: An integer overflow vulnerability was found in the DHCP server. When the "option_code_hash_lookup()" function is called from "add_option()", it increases the option's "refcount" field. However, there is not a corresponding call to "option_dereference()" to decrement the "refcount" field. The "add_option()" function is only used in server responses to lease query packets. Each lease query response calls this function for several options. Hence, a DHCP server configured with "allow lease query," a remote machine with access to the server, can send lease queries for the same lease multiple times, leading to the "add_option()" function being called repeatedly. This issue could cause the reference counters to overflow and the server to abort or crash.
Statement: Vulnerable servers are network accessible to an attacker and configured to allow and process lease queries.

Internally, reference counters are integers and thus overflow at 2^31 references, so even at 1000 lease query responses per second, it would take more than three weeks to crash the server.
Mitigation: Possible workaround - Disable lease query on the server for DHCPv4 or restart the server periodically.
CVE-2022-36763 (Moderate severity, published 2024-01-08)
CVSS score: 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:H)
CWE: CWE-680
Description: A heap buffer overflow flaw was found via the Tcg2MeasureGptTable() function in EDK2, arising from inadequate validation of the GPT Primary Header, presenting a minor risk to confidentiality and integrity. The primary consequence is likely a crash or denial of service. This issue may allow a local attacker to craft a GPT table, causing an integer overflow and consequent buffer overflow.
Statement: Red Hat has protection mechanisms in place against buffer overflows, such as FORTIFY_SOURCE, Position Independent Executables or Stack Smashing Protection.
