CVE-2026-64121

CVE-2026-64121 affects the Linux kernel net:ifb subsystem where per-queue RX/TX stats were allocated using dev->num_tx_queues but walked using dev->real_num_rx_queues and dev->real_num_tx_queues. This mismatch could let ethtool stat walks read past allocated tx_private entries, triggerin...

Astra Linux – Vulnerability in Linux 5.10, Linux

A issue was discovered in the Linux kernel through version 5.16-rc6. The function netvscgetethtoolstats in the drivers/net/hyperv/netvscdrv.c file lacks a check on the return value of kvmallocarray, which can lead to a null pointer derefrence...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: mvneta: fix calls to pagepoolgetstats Calling pagepoolgetstats in the mvneta driver without proper checks leads to kernel crashes. Firstly, the page pool is only available if the bm is not being used. The page pool is also n...

SUSE CVE-2026-31505

In the Linux kernel, the following vulnerability has been resolved: iavf: fix out-of-bounds writes in iavfgetethtoolstats iavf incorrectly uses realnumtxqueues for ETHSSSTATS. Since the value could change in runtime, we should use numtxqueues instead. Moreover iavfgetethtoolstats uses...

CVE-2026-31494

A flaw was found in the Linux kernel's macb network driver. A local user can exploit this vulnerability due to an out-of-bounds write in the gemgetethtoolstats function. This occurs when the driver incorrectly copies data using the maximum number of queues instead of the active number, leading to...

CVE-2026-31505

The CVE-2026-31505 issue affects the Linux kernel iavf driver: out-of-bounds writes occur because iavf_get_ethtool_stats() uses real_num_tx_queues for ETH_SS_STATS while other paths use num_tx_queues, enabling memory corruption when ethtool -L and ethtool -S run concurrently. The fix is to use im...
