CVE ID :CVE-2026-50258 Published : June 5, 2026, 12:16 p.m. | 2 hours, 16 minutes ago Description :A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups but CheckKeyTypes() does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift levels and trigger stack overflows. This is caused by an incomplete fix of CVE-2025-26597. This may be used to crash the server, or for privilege escalation if the X server runs as root.

CVE ID :CVE-2026-50261 Published : June 5, 2026, 12:16 p.m. | 2 hours, 16 minutes ago Description :A use-after-free flaw was found in the X.Org X server and Xwayland in SyncChangeCounter(). A client that sets up multiple SyncCounters can trigger a use-after-free when destroying those counters via a second client connection while changing those counters. This may be used to crash the server, or for privilege escalation if the X server runs as root. Severity: 7.8 | HIGH Visit the link for more details, such as CVSS details, affected products, timeline, and more...

A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client that sets up multiple fence triggers can trigger a use-after-free function pointer call. An attacker would connect to the X server to set up a fence and await that fence, then a second X connection destroys the fence, causing the use-after-free. This may be used to crash the server, or for privilege escalation if the X server runs as root.

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name between 257 and 1023 bytes causes the X server to copy that name into the undersized stack buffer without further checks. This may be used to crash the server, or for privilege escalation if the X server runs as root.

CVE ID :CVE-2026-25659 Published : June 5, 2026, 12:16 p.m. | 2 hours, 16 minutes ago Description :Ericsson Packet Core Gateway (PCG) versions prior to 1.30 contain an Improper Handling of Missing Values (CWE-230) vulnerability where an attacker continuously sending a specially crafted message can cause service degradation. The impact continues as long the attack persists but the system recovers from the crashes when the attack stops.

CVE ID :CVE-2026-11346 Published : June 5, 2026, 12:16 p.m. | 2 hours, 16 minutes ago Description :A Server-Side Request Forgery (SSRF) vulnerability in the custom process creation feature of linqi allows an authenticated attacker to probe internal network components. By crafting a specific process containing an HTTP Request component, an attacker can force the server to send arbitrary HTTP requests. By observing the varying application responses (Success, Failed, or 504 Gateway Time-out), the attacker can determine the status of internal ports, leading to internal network reconnaissance.

CVE ID :CVE-2026-11345 Published : June 5, 2026, 12:16 p.m. | 2 hours, 16 minutes ago Description :An Improper Authentication vulnerability in the /api/Cdn/GetFile endpoint of linqi allows unauthenticated, remote attackers to bypass file access controls. The ValidateAnonFileAccess function incorrectly grants access if an 'AnonFile' query parameter containing exactly 256 characters is provided. While this flaw allows bypassing the intended authorization check, the actual security impact is negligible; the exposed resources are strictly limited to minified JavaScript and CSS files that contain no sensitive data and are already publicly accessible via a standard CDN.
