EUVD-2026-55547

In the Linux kernel, the following vulnerability has been resolved: sctp: close UDP tunnel sockets during netns teardown procsctpdoudpport starts per-net SCTP UDP tunneling sockets when net.sctp.udpport is set, and stops/restarts them when the sysctl value changes. The netns exit path does not st...

CVE-2026-68161

CVE-2026-68161 affects the Linux kernel SCTP UDP tunnel implementation. When net.sctp.udp_port is configured, proc_sctp_do_udp_port() creates per-net SCTP UDP tunneling sockets; the netns exit path did not stop these sockets, so a namespace could be torn down with the UDP tunnel sockets still ins...

EUVD-2026-55526

In the Linux kernel, the following vulnerability has been resolved: net: slip: serialize receive against buffer reallocation slreallocbufs replaces rbuff and updates buffsize while holding sl-lock. slipreceivebuf reads those fields and writes through rbuff without holding the lock. An MTU change...

CVE-2026-68142

The Linux kernel vulnerability CVE-2026-68142 affects the geneve tunnel implementation. It occurs in the changelink flow for Geneve devices where the boundary of CAP_NET_ADMIN is checked only against the dev_net, allowing an attacker privileged in that netns but not in the geneve->net underlay...

EUVD-2026-55518

In the Linux kernel, the following vulnerability has been resolved: net/x25: fix use-after-free in x25killbyneigh x25killbyneigh walks the global X.25 socket list looking for sockets attached to a terminating neighbour. x25listlock protects list membership while the lookup is in progress, but it...

EUVD-2026-55515

In the Linux kernel, the following vulnerability has been resolved: ptp: ptps390: Add missing facility check Only register the physical clock when facility 28 is installed and PTFF QAF returns that PTFF QPT is available...

CVE-2026-68134

CVE-2026-68134 pertains to the Linux kernel, specifically the ptp_s390 driver. The issue arises from a missing facility check when registering the physical clock, which could occur unless facility 28 is installed and PTFF QAF indicates that PTFF QPT is available. The fix adds the required facilit...

CVE-2026-68133

The CVE concerns the Linux kernel ice driver’s PTP handling. A PF reset when PTP state is ICE_PTP_UNINIT could cause ice_ptp_rebuild() to set the state to ICE_PTP_ERROR, producing a PTP release call trace during driver unload (ice_ptp_release -> ice_deinit_features.part.0 -> ice_remove). Th...

EUVD-2026-55511

In the Linux kernel, the following vulnerability has been resolved: ksmbd: defer destroyprevioussession until after NTLM authentication In ntlmauthenticate, destroyprevioussession is called using a user pointer resolved from the client-supplied NTLM blob username field before the NTLMv2 response ...

CVE-2026-68121

The CVE-2026-68121 issue affects the Linux kernel PPPoE path. During pppoe_sendmsg(), a pointer to the PPPoE header is saved before dev_hard_header(); if a device header callback reallocates the skb head (e.g., when a non-Ethernet port is added to a team during a blocked copy_from_user()), PPPoE ...

EUVD-2026-55501

In the Linux kernel, the following vulnerability has been resolved: rtase: Workaround for TX hang caused by hardware packet parsing The hardware performs packet parsing before packet transmission. Parsing incomplete IPv4, IPv6, TCP, or UDP headers may trigger a TX hang because the hardware parser...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfAppUpdateWindowFromSurface reused a cached XImage, where the data pointer referred to an RDPGFX surface buffer that had been freed. This was because gdiDeleteSurface freed surface-data without invalidating...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: net/handshake: Duplicate handshake cancellations cause a socket leak. When a handshake request is cancelled, it is removed from the handshakenet-hnrequests list, but it remains in the handshakerhashtbl until it is destroyed. If a...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, in the resizevbarentry function in libfreerdp/codec/clear.c, vBarEntry-size was updated to vBarEntry-count before the winpralignedrecalloc call. If the realloc call fails, the size is inflated, and the pixel...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: mptcp: Fixed the detection of protocol fallback using BPF. The sockmap feature allows for BPF syscall from user space, or based on BPF sockops, replacing the skprot of sockets during protocol stack processing with sockmap’s...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Validates the owner of the durable handle upon reconnection. Currently, ksmbd does not verify whether the user attempting to reconnect to a durable handle is the same user who originally opened the file. This allows any...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: In the inet section, RAW sockets using IPPROTORAW must drop incoming ICMP packets. Yizhou Zhao reported that simply having a RAW socket with the protocol set to IPPROTORAW 255 was dangerous. The code example: socketAFINET, SOCKRA...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, there was a heap-buffer-overflow vulnerability at 24 bytes before the allocation, in the function winpralignedoffsetrecalloc. This issue has been fixed in version 3.24.2...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, an unvalidated authlength field read from the network triggered a WINPRASSERT failure in rtsreadauthverifiernochecks, causing any FreeRDP client connecting through a malicious RDP Gateway to crash with...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. The ainputsendinputevent function caches the channelcallback in a local variable and then uses it without synchronization. A concurrent closure of a channel can free or reinitialize the callback, resulting in an use-after-free...
