Details

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

KVM: x86: Free kvm_cpuid_entry2 array on post-KVM_RUN KVM_SET_CPUID{,2}

Free the "struct kvm_cpuid_entry2" array on successful post-KVM_RUN KVM_SET_CPUID{,2} to fix a memory leak, the callers of kvm_set_cpuid() free the array only on failure.

GHSA-V7XJ-X69J-92C7

Vulnerability from github – Published: 2022-05-24 17:35 – Updated: 2022-05-24 17:35
VLAI
Details

in SetImageExtent() of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because the code which checks for the proper image depth size does not reset the size in the event there is an invalid size. The patch resets the depth to a proper size before throwing an exception. The memory leak can be triggered by a crafted input file that is processed by ImageMagick and could cause an impact to application reliability, such as denial of service. This flaw affects ImageMagick versions prior to 7.0.9-0.

Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-13 18:31

Details

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

octeontx2-af: Fix mcam entry resource leak

The teardown sequence in FLR handler returns if no NIX LF is attached to PF/VF because it indicates that graceful shutdown of resources already happened. But there is a chance of all allocated MCAM entries not being freed by PF/VF. Hence free mcam entries even in case of detached LF.

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

wifi: mac80211: fix potential sta-link leak

When a station is allocated, links are added but not set to valid yet (e.g. during connection to an AP MLD), we might remove the station without ever marking links valid, and leak them. Fix that.

Multiple memory leaks in the dtls1_process_out_of_seq_message function in ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote attackers to cause a denial of service (memory consumption) via DTLS records that (1) are duplicates or (2) have sequence numbers much greater than current sequence numbers, aka "DTLS fragment handling memory leak."

GHSA-V99V-6WP3-34RF

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-11-05 17:48
VLAI
Details

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

wifi: ath12k: Avoid memory leak while enabling statistics

Driver uses monitor destination rings for extended statistics mode and standalone monitor mode. In extended statistics mode, TLVs are parsed from the buffer received from the monitor destination ring and assigned to the ppdu_info structure to update per-packet statistics. In standalone monitor mode, along with per-packet statistics, the packet data (payload) is captured, and the driver updates per MSDU to mac80211.

When the AP interface is enabled, only extended statistics mode is activated. As part of enabling monitor rings for collecting statistics, the driver subscribes to HAL_RX_MPDU_START TLV in the filter configuration. This TLV is received from the monitor destination ring, and kzalloc for the mon_mpdu object occurs, which is not freed, leading to a memory leak. The kzalloc for the mon_mpdu object is only required while enabling the standalone monitor interface. This causes a memory leak while enabling extended statistics mode in the driver.

Fix this memory leak by removing the kzalloc for the mon_mpdu object in the HAL_RX_MPDU_START TLV handling. Additionally, remove the standalone monitor mode handlings in the HAL_MON_BUF_ADDR and HAL_RX_MSDU_END TLVs. These TLV tags will be handled properly when enabling standalone monitor mode in the future.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

Vulnerability from github – Published: 2022-05-24 17:12 – Updated: 2023-02-03 21:30
VLAI
Details

Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because a circuit-padding machine can be negotiated twice on the same circuit.

Mitigation MIT-41
Implementation

Strategy: Libraries or Frameworks

  • Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
  • For example, glibc in Linux provides protection against free of invalid pointers.
  • When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
  • To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
Mitigation
Architecture and Design

Use an abstraction library to abstract away risky APIs. Not a complete solution.

Mitigation
Architecture and Design Build and Compilation

Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
