Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel before version 5.8.10. The file virt/kvm/kvmmain.c contains a memory leak in kvmiobusunregisterdev due to a kmalloc failure, identified as CID-f65886606c2d...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: Handling of integer overflows in kmallocreserve The committed change was as follows: c ptr = kmallocsize; if ptr size = ksizeptr; size = kmallocsizeroundupsize; ptr = kmallocsize; This caused various crashes, as reported ...

CVE-2026-74576

A flaw was found in the Linux kernel's memory management. This vulnerability allows for unbounded recursion in the slab free path, a process where the kernel manages and releases small blocks of memory. When certain kernel memory allocation caches kmalloc caches form a cycle during internal data...

CVE-2026-74576

Summary of CVE-2026-74576 (Linux kernel) : The vulnerability stems from the slab allocator allowing unbounded recursion in the free path due to cycles formed when obj_exts arrays are allocated across KMALLOC_NORMAL caches. Specifically, slabs can form a cycle by allocating each other’s obj_exts a...

CVE-2026-74528

The CVE refers to the Linux kernel Bluetooth subsystem: hci_sync in the hci_past_sync() callback, which previously could dereference freed pointers to hci_conn_valid() due to kmalloc reuse. The fix holds a reference count on the connection to ensure resources remain valid, preventing use-after-fr...
