kernel: gfs2: Fix use-after-free in iomap inline data write path
A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...
kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count()
A use-after-free flaw was found in the Linux kernel's iSCSI target subsystem. In the iscsitdecconnusagecount function, complete is called while still holding the conn-connusagelock spinlock. The waiting thread such as iscsitcloseconnection may wake up immediately and free the iscsitconn structure...

CVE-2025-59617
CVE-2025-59617 describes a memory corruption issue (Use After Free) in Computer Vision when multiple IOCTL calls reuse the same buffer file descriptor input. The CVSS metrics indicate a local attacker with high attack complexity and low privileges, requiring user interaction, with impact to integ...
CVE-2025-59617 Use After Free in Computer Vision
Memory Corruption when processing multiple IOCTL calls with the same buffer file descriptor input...
CVE-2025-59616
CVE-2025-59616 : Memory corruption (use-after-free) when processing multiple IOCTL calls using the same buffer file descriptor input, due to accessing memory that has already been freed. Affects the described Computer Vision context; underlying issue is use-after-free in the handling of repeated ...

Memory Corruption when processing multiple IOCTL calls with the same buffer file descriptor input due to accessing already freed memory...
CVE-2025-59615
CVE-2025-59615 describes a Use-After-Free memory corruption in computer vision code triggered by device IOCTL operations for mapping/unmapping persistent memory buffers, caused by improper synchronization. The issue is rated CVSS v3.1 base score 6.6 (Medium): LOCAL attack, HIGH exploit complexity...
CVE-2026-9080
A flaw was found in libcurl. When curleasypause is called within the event-based CURLMOPTSOCKETFUNCTION callback, a use-after-free vulnerability is triggered. This occurs because libcurl attempts to store a flag using a pointer to memory that has already been freed. An attacker could potentially...
16-Year-Old Linux KVM Flaw Lets Guest VMs Escape to Host on Intel and AMD x86 Systems
A use-after-free bug in Linux's KVM hypervisor can be triggered from a guest virtual machine to corrupt the shadow-page state of the host kernel that runs it. Dubbed 'Januscape' and tracked as CVE-2026-53359, the flaw sits in the shadow MMU code that KVM shares across both Intel and AMD. The publ...
BIT-PYTHON-2026-6100 Use-after-free in lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile after re-use under memory pressure
Use-after-free UAF was possible in the lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile when a memory allocation fails with a MemoryError and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the dangling...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold
A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established
A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...
CVE-2026-14788
A flaw was found in radare2. A local attacker could trigger a use-after-free vulnerability within the rcorebinload function. This issue can lead to memory corruption, resulting in a denial of service DoS for the application. Mitigation To mitigate this issue, ensure that only trusted users have...
CVE-2026-14760
A flaw was found in radareorg radare2. This vulnerability, a use-after-free, affects the regprofile Handler component. A local attacker can exploit this flaw by performing a specific manipulation, which could lead to a denial of service, making the application unavailable. Mitigation To mitigate...
