CVE	Sev	Risk	CVSS	EPSS	Published	Description
CVE-2026-6870	Med	0.36	5.5	0.00	Apr 30, 2026	GSM RP protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-6524	Med	0.36	5.5	0.00	Apr 30, 2026	MySQL protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-27300	Med	0.36	5.5	0.00	Apr 14, 2026	Adobe Framemaker versions 2022.8 and earlier are affected by an Access of Uninitialized Pointer vulnerability that could lead to memory exposure. An attacker could leverage this vulnerability to disclose sensitive information. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2024-49938	Med	0.36	5.5	0.00	Oct 21, 2024	In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit Syzbot points out that skb_trim() has a sanity check on the existing length of the skb, which can be uninitialised in some error paths. The intent here is clearly just to reset the length to zero before resubmitting, so switch to calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length() already contains a call to skb_reset_tail_pointer(), so remove the redundant call. The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.
CVE-2006-0054	Med	0.35	5.3	0.03	Jan 11, 2006	The ipfw firewall in FreeBSD 6.0-RELEASE allows remote attackers to cause a denial of service (firewall crash) via ICMP IP fragments that match a reset, reject or unreach action, which leads to an access of an uninitialized pointer.
CVE-2026-6778	Med	0.34	5.3	0.00	Apr 21, 2026	Invalid pointer in the Audio/Video: Playback component. This vulnerability was fixed in Firefox 150 and Thunderbird 150.
CVE-2026-2100	Med	0.34	5.3	0.00	Mar 26, 2026	A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states.
CVE-2010-1818		0.09	—	0.77	Aug 31, 2010	The IPersistPropertyBag2::Read function in QTPlugin.ocx in Apple QuickTime 6.x, 7.x before 7.6.8, and other versions allows remote attackers to execute arbitrary code via the _Marshaled_pUnk attribute, which triggers unmarshalling of an untrusted pointer.
CVE-2007-4639		0.05	—	0.19	Aug 31, 2007	EnterpriseDB Advanced Server 8.2 does not properly handle certain debugging function calls that occur before a call to pldbg_create_listener, which allows remote authenticated users to cause a denial of service (daemon crash) and possibly execute arbitrary code via a SELECT statement that invokes a pldbg_ function, as demonstrated by (1) pldbg_get_stack and (2) pldbg_abort_target, which triggers use of an uninitialized pointer.
CVE-2014-1564		0.04	—	0.14	Sep 3, 2014	Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 do not properly initialize memory for GIF rendering, which allows remote attackers to obtain sensitive information from process memory via crafted web script that interacts with a CANVAS element associated with a malformed GIF image.
CVE-2009-1415		0.04	—	0.18	Apr 30, 2009	lib/pk-libgcrypt.c in libgnutls in GnuTLS before 2.6.6 does not properly handle invalid DSA signatures, which allows remote attackers to cause a denial of service (application crash) and possibly have unspecified other impact via a malformed DSA key that triggers a (1) free of an uninitialized pointer or (2) double free.
CVE-2009-0846		0.04	—	0.50	Apr 9, 2009	The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.
CVE-2007-2442		0.03	—	0.43	Jun 26, 2007	The gssrpc__svcauth_gssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup.
CVE-2007-1213		0.03	—	0.02	Apr 4, 2007	The TrueType Fonts rasterizer in Microsoft Windows 2000 SP4 allows local users to gain privileges via crafted TrueType fonts, which result in an uninitialized function pointer.
CVE-2009-1721		0.02	—	0.25	Jul 31, 2009	The decompression implementation in the Imf::hufUncompress function in OpenEXR 1.2.2 and 1.6.1 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors that trigger a free of an uninitialized pointer.
CVE-2007-4000		0.02	—	0.25	Sep 5, 2007	The kadm5_modify_policy_internal function in lib/kadm5/srv/svr_policy.c in the Kerberos administration daemon (kadmind) in MIT Kerberos 5 (krb5) 1.5 through 1.6.2 does not properly check return values when the policy does not exist, which might allow remote authenticated users with the "modify policy" privilege to execute arbitrary code via unspecified vectors that trigger a write to an uninitialized pointer.
CVE-2006-6143		0.02	—	0.25	Dec 31, 2006	The RPC library in Kerberos 5 1.4 through 1.4.4, and 1.5 through 1.5.1, as used in Kerberos administration daemon (kadmind) and other products that use this library, calls an uninitialized function pointer in freed memory, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.
CVE-2009-0040		0.01	—	0.08	Feb 22, 2009	The PNG reference library (aka libpng) before 1.0.43, and 1.2.x before 1.2.35, as used in pngcrush and other applications, allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file that triggers a free of an uninitialized pointer in (1) the png_read_png function, (2) pCAL chunk handling, or (3) setup of 16-bit gamma tables.
CVE-2011-1814		0.00	—	0.01	Jun 9, 2011	Google Chrome before 12.0.742.91 attempts to read data from an uninitialized pointer, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.
