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-2025-59615

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
