CVE-2024-36890 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: mm/slab: make __free(kfree) accept error pointers Currently, if an automatically freed allocation is an error pointer that will lead to a crash. An example of this is in wm831x_gpio_dbg_show(). 171 char *label __free(kfree) = gpiochip_dup_line_label(chip, i); 172 if (IS_ERR(label)) { 173 dev_err(wm831x->dev, "Failed to duplicate label\n"); 174 continue; 175 } The auto clean up function should check for error pointers as well, otherwise we're going to keep hitting issues like this.
CVE-2024-35832 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: bcachefs: kvfree bch_fs::snapshots in bch2_fs_snapshots_exit bch_fs::snapshots is allocated by kvzalloc in __snapshot_t_mut. It should be freed by kvfree not kfree.

CVE-2024-2955 2 Fedoraproject, Wireshark 2 Fedora, Wireshark 2026-06-17 N/A 7.8 HIGH
T.38 dissector crash in Wireshark 4.2.0 to 4.0.3 and 4.0.0 to 4.0.13 allows denial of service via packet injection or crafted capture file
CVE-2024-25079 1 Insyde 1 Insydeh2o 2026-06-17 N/A 7.4 HIGH
A memory corruption vulnerability in HddPassword in Insyde InsydeH2O kernel 5.2 before 05.29.09, kernel 5.3 before 05.38.09, kernel 5.4 before 05.46.09, kernel 5.5 before 05.54.09, and kernel 5.6 before 05.61.09 could lead to escalating privileges in SMM.
CVE-2023-4883 1 Open5gs 1 Open5gs 2026-06-17 N/A 7.5 HIGH
Invalid pointer release vulnerability. Exploitation of this vulnerability could allow an attacker to interrupt the correct operation of the service by sending a specially crafted json string to the VNF (Virtual Network Function), and triggering the ogs_sbi_message_free function, which could cause a service outage.
CVE-2023-43532 1 Qualcomm 26 Fastconnect 6700, Fastconnect 6700 Firmware, Fastconnect 6900 and 23 more 2026-06-17 N/A 8.4 HIGH
Memory corruption while reading ACPI config through the user mode app.
CVE-2023-34312 1 Tencent 2 Qq, Tim 2026-06-17 N/A 7.8 HIGH
In Tencent QQ through 9.7.8.29039 and TIM through 3.4.7.22084, QQProtect.exe and QQProtectEngine.dll do not validate pointers from inter-process communication, which leads to a write-what-where condition.
CVE-2023-31082 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
An issue was discovered in drivers/tty/n_gsm.c in the Linux kernel 6.2. There is a sleeping function called from an invalid context in gsmld_write, which will block the kernel. Note: This has been disputed by 3rd parties as not a valid vulnerability.
CVE-2023-25565 1 Gss-ntlmssp Project 1 Gss-ntlmssp 2026-06-17 N/A 7.5 HIGH
GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to version 1.2.0, an incorrect free when decoding target information can trigger a denial of service. The error condition incorrectly assumes the `cb` and `sh` buffers contain a copy of the data that needs to be freed. However, that is not the case. This vulnerability can be triggered via the main `gss_accept_sec_context` entry point. This will likely trigger an assertion failure in `free`, causing a denial-of-service. This issue is fixed in version 1.2.0.
CVE-2023-0459 1 Linux 1 Linux Kernel 2026-06-17 N/A 6.5 MEDIUM
Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec allowing a user to bypass the "access_ok" check and pass a kernel pointer to copy_from_user(). This would allow an attacker to leak information. We recommend upgrading beyond commit 74e19ef0ff8061ef55957c3abd71614ef0f42f47
CVE-2022-48425 1 Linux 1 Linux Kernel 2026-06-17 N/A 7.8 HIGH
In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT flags before replaying logs.
CVE-2022-46486 1 Scontain 1 Scone 2026-06-17 N/A 5.5 MEDIUM
A lack of pointer-validation logic in the __scone_dispatch component of SCONE before v5.8.0 for Intel SGX allows attackers to access sensitive information.
CVE-2022-42309 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2026-06-17 N/A 8.8 HIGH
Xenstore: Guests can crash xenstored Due to a bug in the fix of XSA-115 a malicious guest can cause xenstored to use a wrong pointer during node creation in an error path, resulting in a crash of xenstored or a memory corruption in xenstored causing further damage. Entering the error path can be controlled by the guest e.g. by exceeding the quota value of maximum nodes per domain.
CVE-2022-41691 1 F5 2 Big-ip Advanced Web Application Firewall, Big-ip Application Security Manager 2026-06-17 N/A 7.5 HIGH
When a BIG-IP Advanced WAF/ASM security policy is configured on a virtual server, undisclosed requests can cause the bd process to terminate.
CVE-2022-37451 2 Exim, Fedoraproject 2 Exim, Fedora 2026-06-17 N/A 7.5 HIGH
Exim before 4.96 has an invalid free in pam_converse in auths/call_pam.c because store_free is not used after store_malloc.
CVE-2022-31625 2 Debian, Php 2 Debian Linux, Php 2026-06-17 6.8 MEDIUM 8.1 HIGH
In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of service.
CVE-2022-2521 2 Debian, Libtiff 2 Debian Linux, Libtiff 2026-06-17 N/A 6.5 MEDIUM
It was found in libtiff 4.4.0rc1 that there is an invalid pointer free operation in TIFFClose() at tif_close.c:131 called by tiffcrop.c:2522 that can cause a program crash and denial of service while processing crafted input.
CVE-2022-28203 2 Debian, Mediawiki 2 Debian Linux, Mediawiki 2026-06-17 N/A 7.5 HIGH
A denial-of-service issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2. When many files exist, requesting Special:NewFiles with actor as a condition can result in a very long running query.
CVE-2022-26942 1 Motorola 4 Mtm5400, Mtm5400 Firmware, Mtm5500 and 1 more 2026-06-17 N/A 8.2 HIGH
The Motorola MTM5000 series firmwares lack pointer validation on arguments passed to trusted execution environment (TEE) modules. Two modules are used, one responsible for KVL key management and the other for TETRA cryptographic functionality. In both modules, an adversary with non-secure supervisor level code execution can exploit the issue in order to gain secure supervisor code execution within the TEE. This constitutes a full break of the TEE module, exposing the device key as well as any TETRA cryptographic keys and the confidential TETRA cryptographic primitives.
CVE-2022-25725 1 Qualcomm 134 Ar8035, Ar8035 Firmware, Csrb31024 and 131 more 2026-06-17 N/A 6.2 MEDIUM
Denial of service in MODEM due to improper pointer handling
