NULL dereference in iwl driver

The iwl_set_rate function in compatible/iwl3945-base.c in iwlwifi 1.1.21 and earlier dereferences an iwl_get_hw_mode return value without checking for NULL, which might allow remote attackers to cause a denial of service (kernel panic) via unspecified vectors during module initialization.

The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold and SP1, and Server 2008 Gold does not properly validate data sent from user mode, which allows local users to gain privileges via a crafted PE .exe file that triggers a NULL pointer dereference during chain traversal, aka "Windows Kernel NULL Pointer Dereference Vulnerability."

Seamonkey: NULL pointer dereference in GIF decoder

The nsGIFDecoder2::GifWrite function in decoders/gif/nsGIFDecoder2.cpp in libpr0n in Mozilla Firefox before 3.5.5 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an animated GIF file with a large image size, a different vulnerability than CVE-2009-3373.

boost regular expression NULL dereference flaw

The get_repeat_type function in basic_regex_creator.hpp in the Boost regex library (aka Boost.Regex) in Boost 1.33 and 1.34 allows context-dependent attackers to cause a denial of service (NULL dereference and crash) via an invalid regular expression.

kernel: NULL ptr dereference in multiple network drivers due to missing checks in tty code

The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.

binutils: Binutils: Denial of Service via crafted ELF binary processing

GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an invalid pointer free when processing a crafted ELF binary with malformed relocation or symbol data. If dump_relocations returns early due to parsing errors, the internal all_relocations array may remain partially uninitialized. Later, process_got_section_contents() may attempt to free an invalid r_symbol pointer, triggering memory corruption checks in glibc and causing the program to terminate with SIGABRT. No evidence of further memory corruption or code execution was observed; the impact is limited to denial of service. NOTE: this is disputed by third parties because the observed behavior occurred only in pre-release code and did not affect any tagged version.

Windows Remote Access Connection Manager Denial of Service Vulnerability

Null pointer dereference in Windows Remote Access Connection Manager allows an unauthorized attacker to deny service locally.

PCI: endpoint: Avoid creating sub-groups asynchronously

In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: Avoid creating sub-groups asynchronously The asynchronous creation of sub-groups by a delayed work could lead to a NULL pointer dereference when the driver directory is removed before the work completes. The crash can be easily reproduced with the following commands: # cd /sys/kernel/config/pci_ep/functions/pci_epf_test # for i in {1..20}; do mkdir test && rmdir test; done BUG: kernel NULL pointer dereference, address: 0000000000000088 ... Call Trace: configfs_register_group+0x3d/0x190 pci_epf_cfs_work+0x41/0x110 process_one_work+0x18f/0x350 worker_thread+0x25a/0x3a0 Fix this issue by using configfs_add_default_group() API which does not have the deadlock problem as configfs_register_group() and does not require the delayed work handler. [mani: slightly reworded the description and added stable list]

Incorrect JavaScript state machine for generators

The JavaScript engine did not handle closed generators correctly and it was possible to resume them leading to a nullptr deref. This vulnerability was fixed in Firefox 141, Firefox ESR 115.26, Firefox ESR 128.13, Firefox ESR 140.1, Thunderbird 141, Thunderbird 128.13, and Thunderbird 140.1.

ksmbd: fix null pointer dereference error in generate_encryptionkey

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix null pointer dereference error in generate_encryptionkey If client send two session setups with krb5 authenticate to ksmbd, null pointer dereference error in generate_encryptionkey could happen. sess->Preauth_HashValue is set to NULL if session is valid. So this patch skip generate encryption key if session is valid.

Vba32 Antivirus v3.36.0 - Denial of Service (DoS)

Vba32 Antivirus v3.36.0 is vulnerable to a Denial of Service vulnerability by triggering the 0x2220A7 IOCTL code of the Vba32m64.sys driver.

Windows Client-Side Caching Elevation of Privilege Vulnerability

Null pointer dereference in Windows Client-Side Caching (CSC) Service allows an authorized attacker to elevate privileges locally.

DirectX Graphics Kernel Denial of Service Vulnerability

Null pointer dereference in Windows DirectX allows an authorized attacker to deny service locally.

DirectX Graphics Kernel Denial of Service Vulnerability

Null pointer dereference in Windows DirectX allows an authorized attacker to deny service locally.

iccDEV: UB at IccTagLut.cpp

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, there is an Undefined Behavior (UB) issue in IccTagLut.cpp where the code performs member access through a null pointer of type CIccApplyCLUT. This issue has been patched in version 2.3.1.6.

iccDEV: NPD in CIccTagLut16::Write()

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a null-pointer dereference (NPD) in CIccTagLut16::Write() can be triggered when processing a crafted ICC profile (embedded in a TIFF and extracted during iccTiffDump). This issue has been patched in version 2.3.1.6.

iccDEV: UB in CIccCombinedConnectionConditions::CIccCombinedConnectionConditions()

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger Undefined Behavior (UB) via a null-pointer member call in CIccCombinedConnectionConditions::CIccCombinedConnectionConditions() (reported by UBSan as “member call on null pointer of type CIccTagSpectralViewingConditions”). The issue is reachable when running iccApplyNamedCmm with -PCC using a malformed .icc profile. This issue has been patched in version 2.3.1.6.
