Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Take the RTNL lock when necessary before calling xdpsetfeatures. The RTNL lock must be held when calling xdpsetfeatures with a registered netdev, as this call triggers the netdev notifiers. This could occur, for exampl...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: bpf: Enforce expectedattachtype for tailcall compatibility Yinhao et al. recently reported: Our fuzzer tool discovered an uninitialized pointer issue in the bpfprogtestrunxdp function within the Linux kernel’s BPF subsystem. This...
Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: net: veth: The GRO flag is cleared when XDP is disabled, even when the device is disabled. The NETIFFGRO flag is set automatically when XDP is enabled, because both features use the same NAPI mechanism. The logic for clearing the...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: “ice”: fixed the sizing of vsi-txqmap. The approach of having XDP queues per CPU, regardless of the user’s settings, exposed a hidden bug that could occur when the number of Rx queues differs from the number of Tx queues...
Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15
In the Linux kernel, the following vulnerabilities have been resolved: - ice: xsk: disabling TXQ interrupts before flushing hardware settings. - iceqpdis attempts to stop a given queue pair that is a target of xsk pool attach/detach. One of the steps involved disabling interrupts on these queues...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: igc: Avoid returning the frame twice in XDPREDIRECT When a frame cannot be transmitted via XDPREDIRECT e.g., due to a full queue, it is necessary to free the frame by calling xdpreturnframerxnapi. However, this is the...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: xsk: Fixed corrupted packets for XDPSHAREDUMEM. A issue was addressed in the XDPSHAREDUMEM mode, along with the aligned mode, where packets were corrupted for the second and any subsequent sockets bound to the same umem. In other...
Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: net: stmmac: A possible memory leak has been fixed in stmmacdvrprobe. The bitmapfree function should be called to release priv-afxdpzcqps when createsinglethreadworkqueue fails. Otherwise, a memory leak will occur. Therefore, we...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fixed a race condition in cpumap on PREEMPTRT kernels. On PREEMPTRT kernels, the per-CPU xdpbulkqueue can be accessed concurrently by multiple preemptible tasks on the same CPU. The original code assumes that bqenqueue an...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: xsk: Validates the MTU against the usable frame size when binding. The AFXDP binding currently accepts zero-copy pool configurations without verifying that the device’s MTU fits within the usable frame space provided by the UMEM...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fixed invalid buffer access for legacy rq The following crash can occur when using xdpsock in RX mode for legacy rq: the buffer is released in the XDPREDIRECT path, and then again in the driver. This fix sets a fl...
Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: bpf: Ensure that the internal and UAPI bpfredirect flags do not overlap. The bpfredirectinfo is shared between the SKB and XDP redirection paths. Both paths use the same numerical flag values in the ri-flags field specifically,...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: xdp: generate a warning when the calculated tailroom is negative Many Ethernet drivers report that the xdp Rx queue frag size is the same as the DMA write size. However, the only user of this field, namely bpfxdpfragsincreasetail...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: net: ti: icssg-prueth: Fixed a memory leak in XDPDROP for the non-zero-copy mode. Page recycling was removed from the XDPDROP path in emacrunxdp to avoid conflicts with the AFXDP zero-copy mode, which uses xskbufffree instead...
SUSE CVE-2026-46320
In the Linux kernel, the following vulnerability has been resolved: tap: free page on error paths in tapgetuserxdp tapgetuserxdp rejects a frame shorter than ETHHLEN with -EINVAL, and returns -ENOMEM when buildskb fails. Both paths jump to the err label without freeing the page that...
CVE-2026-46322
A flaw was found in the Linux kernel's tun driver. This vulnerability occurs when the buildskb function fails within tunxdpone, leading to a failure to free an allocated memory page. Each such failure results in a memory leak, where a 'page-frag chunk' is not released. Over time, repeated...
