CVE-2026-99211

A flaw was found in the Linux kernel's netlink subsystem. This vulnerability allows an unprivileged local attacker to read uninitialized kernel memory, resulting in information disclosure. The issue occurs because socket buffer headers are not properly reset before applying socket filters during...

Linux Kernel Missing Initialization of a Variable Vulnerability

Linux Kernel contains a missing initialization of a variable vulnerability that could allow for unintended modification of page-cache-backed data via failure to preserve the shared-fragment marker during socket buffer coalescing, causing ESP input processing to decrypt shared fragments in place...

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

In the Linux kernel, the following vulnerability has been resolved: can: j1939: j1939sessionnew: fix skb reference counting Since j1939sessionskbqueue performs an additional skbget operation for each new skb, doing the same operation for the initial skb in j1939sessionnew will prevent refcount...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net:emac/emac-mac: A use-after-free issue was addressed in emacmactxbufsend. In emacmactxbufsend, it calls emactxfilltpd.., skb,... If an error occurs in emactxfilltpd, the skb will be freed via devkfreeskbskb in the error branch...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: can: j1939: fixed Use-after-Free, failed to increment the ref count of the skb while it was in use. This patch addresses a Use-after-Free issue identified by the syzbot. The problem arises when a skb is taken from the per-session...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net: lltemac: Ensure that the skb is freed when it is completely used. By using the TX BD to track the skb pointer, we can efficiently free the skb buffer after the frame has been transmitted. However, to avoid freeing the skb...

In the Linux kernel, the following vulnerability has been resolved: net: netlink: afnetlink: Prevent empty skb by adding a check on len. Adding a check on the len parameter to prevent empty skb. This prevents a division error in the netemenqueue function, which occurs when skb-len=0 and...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Validate length in packet header before skbput When receiving a vsock packet in the guest, only the virtqueue buffer size is validated prior to virtiovsockskbrxput. Unfortunately, virtiovsockskbrxput uses the length...

In the Linux kernel, the following vulnerability has been resolved: In the BPF code, ensure that skb-len != 0 when redirecting a packet to a tunneling device. The syzkaller function managed to trigger another case where skb-len == 0 when entering devqueuexmit. WARNING: CPU: 0, PID: 2470; Location...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: octeonep: Added handling of SKB allocation failures in octepoqprocessrx. The buildskb function returns NULL in case of a memory allocation failure. Therefore, this behavior should be handled within octepoqprocessrx to prevent NUL...

Astra Linux - vulnerability in linux

In the Linux kernel, the following vulnerability has been resolved: net: cdceem: fix tx fixup skb leak When usbnet transmits a skb, it is fixed via eemtxfixup. If skbcopyexpand fails, it returns NULL; consequently, usbnetstartxmit has no chance to free the original skb. The fix involves freeing t...
