CVE-2026-98272

The Linux kernel contains a buffer overflow vulnerability in the mvpp2 driver during page_pool allocation . The issue occurs because the mvpp2_change_mtu() function may call mvpp2_bm_switch_buffers() without verifying if the number of pools (nrxqs * 2) exceeds the MVPP2_BM_MAX_POOLS limit of 8. T...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: BPF: Fixed a memory leak in the LRU and LRUPERCPU hash maps The LRU and LRUPERCPU maps allocate a new element during updates, before locking the target hash table bucket. Immediately afterwards, the maps attempt to lock the bucke...

CVE-2026-98150

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem.
