CVE-2026-74622

A flaw was found in the Linux kernel's 'atlantic' network driver. The aqringrxdeinit function, responsible for deinitializing receive RX buffers, fails to properly free pages and their associated Direct Memory Access DMA mappings for buffers that have been consumed but not yet refilled. This...

CVE-2026-74623

A flaw was found in the Linux kernel's atlantic network driver. When a network interface using this driver is deinitialized while under transmit TX or XDPTX load, certain transmit buffers are not properly released. This oversight leads to a memory leak, which can prevent the proper shutdown of...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: Remove aqnicdeinit when resuming. aqnicdeinit is called during suspension, so we no longer need to call it again when resuming. However, calling it again can lead to another hang issue when resuming from S3. Jul 8...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: Fix DMA mapping for PTP hwts ring Function aqringhwtsrxalloc maps extra AQCFGRXDSDEF bytes for PTP HWTS ring but then generic aqringfree does not take this into account. Create and use a specific function to free...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Net: Atlantic: Fixed an index out of range error in aqvec. The final update statement of the for loop exceeds the array range. The dereference of self-aqveci is not checked, leading to an index out of range error. This issue h...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Net: Atlantic – Eliminate double-free operations in error handling logic. The driver has a logic flaw in ring data allocation/free. In this flaw, aqringfree may be called multiple times within the same ring. This can occur whe...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: atlantic: Fixed handling of fragment overflow in the RX path. The atlantic driver may receive packets with more than MAXSKBFRAGS 17 fragments when handling large multi-descriptor packets. This causes an out-of-bounds writ...

SUSE CVE-2026-74622

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: free RX pages of consumed but not refilled buffers aqringrxdeinit only walks swhead, swtail, the region posted to hardware. Since the page reuse strategy was added, a cleaned RX buffer keeps its page and its DMA...

CVE-2026-74623

CVE-2026-74623 affects the Aquantia Atlantic network driver in the Linux kernel. The root cause is that aq_vec_deinit() drains TX rings with a single aq_ring_tx_clean() call limited to 256 descriptors and stops at hw_head, which no longer advances after hardware and NAPI are stopped. Completed de...

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: free stranded TX buffers on ring deinit aqvecdeinit drains the TX rings with a single aqringtxclean call, which frees at most AQCFGTXCLEANBUDGET 256 descriptors and stops at hwhead, which no longer moves once...

CVE-2026-74622

CVE-2026-74622 is a resource leak in the Linux kernel's Aquantia (AQC) atlantic network driver. The function aq_ring_rx_deinit() only iterates over the [sw_head, sw_tail) region of the RX ring, but since the page reuse strategy was introduced, consumed-but-not-yet-refilled buffers reside in the c...
