CWE: CWE-99
Description: In the Linux kernel, the following vulnerability has been resolved:

net: lantiq: fix memory corruption in RX ring

In a situation where memory allocation or dma mapping fails, an
invalid address is programmed into the descriptor. This can lead
to memory corruption. If the memory allocation fails, DMA should
reuse the previous skb and mapping and drop the packet. This patch
also increments rx drop counter.

CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-121
Description: In the Linux kernel, the following vulnerability has been resolved:

powerpc/32: Fix hardlockup on vmap stack overflow

Since the commit c118c7303ad5 ("powerpc/32: Fix vmap stack - Do not
activate MMU before reading task struct") a vmap stack overflow
results in a hard lockup. This is because emergency_ctx is still
addressed with its virtual address allthough data MMU is not active
anymore at that time.

Fix it by using a physical address instead.
Statement: Red Hat Enterprise Linux is not impacted by this CVE, as the vulnerability in question does not affect the specific versions or configurations of the Linux kernel used in its distributions. This ensures that users of Red Hat Enterprise Linux are not exposed to the potential risks associated with this issue, and no further action or mitigation is necessary for systems running this operating system.
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-2021-3622 (Low severity, published 2021-08-01)
CVSS score: 4.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CWE: CWE-400
Description: A flaw was found in the hivex library. This flaw allows an attacker to input a specially crafted Windows Registry (hive) file, which would cause hivex to recursively call the _get_children() function, leading to a stack overflow. The highest threat from this vulnerability is to system availability.
Statement: Any external program using the hivex library could be exposed to partial unavailability in case of a crash where a user can always retry the operation. As for libguestfs, a crash in hivex would not result in libguestfs crashing.
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.

CVSS score: 2.5 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L)
CWE: CWE-911
Description: In the Linux kernel, the following vulnerability has been resolved:

sit: do not call ipip6_dev_free() from sit_init_net()

ipip6_dev_free is sit dev->priv_destructor, already called
by register_netdevice() if something goes wrong.

Alternative would be to make ipip6_dev_free() robust against
multiple invocations, but other drivers do not implement this
strategy.

CVSS score: 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
CWE: CWE-119
Description: A flaw was found in the ptp4l program of the linuxptp package. A missing length check when forwarding a PTP message between ports allows a remote attacker to cause an information leak, crash, or potentially remote code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Mitigation: Only attackers that can connect to the `ptp4l` service can exploit this vulnerability. If `ptp4l` is bound only to a private network interface, or is protected by firewall rules to block incoming PTP management messages, the attack surface is correspondingly limited. When using the UDP IPv4 or IPv6 network transport, the following tcpdump filter can be used to detect PTP management messages:

```
(port 319 or port 320) and udp[8]&0xf=0xd
```
CVE-2021-33574 (Low severity, published 2021-05-20)

CWE: CWE-416
Description: The mq_notify function in the GNU C Library (aka glibc) has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact.
Statement: In order to mount a minimal attack using this flaw, an attacker needs many pre-requisites to be able to even crash a program using this mq_notify bug:

1. The program call to mq_notify needs to be controlled by the attacker
2. The program must provide attributes to control creation of the notification thread in mq_notify
3. The program must have the race condition where it may potentially destroy the notification thread attributes before the notification thread is created
4. The program must set CPU affinity of the notification thread to actually cause the use-after-free dereference

There are no known applications that have *all* these pre-requisites.

CWE: CWE-281
Description: A flaw was found in zstd. While the final file mode is reflective of the input file, when compressing or uncompressing, the file can temporarily gain greater permissions than the input and potentially leading to security issues (especially if large files are being handled).
Statement: In OpenShift Container Platform (OCP) the zstd package was delivered in OCP 4.3 which is already end of life.

This vulnerability can be considered low severity rather than moderate due to the fact that the elevated file permissions are only temporary and only exist during the compression or decompression process. Once the operation completes, the file permissions revert to their intended state, mirroring those of the input file. The risk is further minimized by the fact that the exposure window is brief, and the elevated permissions are not persistent. Additionally, the issue only arises during the processing of files, and only those with larger sizes or more involved operations would be at risk.
