DEBIAN-CVE-2026-56787

RTKLIB through 2.4.3 contains an off-by-one out-of-bounds read vulnerability in the decodessr3 function at src/rtcm3.c:1446 that allows remote attackers to trigger a global buffer overflow via crafted RTCM3 SSR messages with attacker-controlled signal mode fields. Remote attackers can exploit thi...

DEBIAN-CVE-2026-56788

RTKLIB through 2.4.3 contains an out-of-bounds read vulnerability in getcodepri function when processing unrecognized RINEX observation codes, allowing attackers to trigger denial of service. Crafted RINEX files with unknown observation types cause negative array indexing into the codepris table,...

Heap buffer overread in wcPKCS7DecodeEnvelopedData when parsing crafted PKCS7 EnvelopedData. This could theoretically be triggered by attacker-supplied data delivered via S/MIME or CMS...

DEBIAN-CVE-2026-57453

Vim is an open source, command line text editor. From 9.1.1784 until 9.2.0678, when the bundled zip plugin autoload/zip.vim falls back to PowerShell to browse, read, extract, update or delete entries in a zip archive, it builds the PowerShell command by inserting archive entry names that are quot...

DEBIAN-CVE-2026-55892

Vim is an open source, command line text editor. Prior to 9.2.0662, the dumpprefixes function in src/spell.c walks a spell-file prefix trie iteratively with a depth counter while dumping the prefixes that apply to a word. The counter is bounded only by the trie structure itself; it is never check...

DEBIAN-CVE-2026-57235

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::NodeSet and its alias slice checked the requested index against the node set's bounds using a 32-bit-truncated copy of the index. A large negative index could pass the check and then...

DEBIAN-CVE-2026-42004

An attacker can send a crafted EDNS OPT record that will be ignored by DNSdist’s filtering rules, but will be rewritten as a valid OPT record when EDNS Client Subnet is inserted, causing the backend to see the EDNS options that DNSdist did not filter...

DEBIAN-CVE-2026-40211

An attacker can send crafted DNS over HTTP/3 queries, triggering an exception that prevents some buffer from being freed right away. The buffer will be freed at the end of the QUIC connection, but on some setups it might be possible to open enough concurrent DoH3 streams to trigger an out-of-memo...

DEBIAN-CVE-2026-53273

In the Linux kernel, the following vulnerability has been resolved: tee: optee: prevent use-after-free when the client exits before the supplicant Commit 70b0d6b0a199 "tee: optee: Fix supplicant wait loop" made the client wait as killable so it can be interrupted during shutdown or after a...

DEBIAN-CVE-2026-53261

In the Linux kernel, the following vulnerability has been resolved: devlink: Release nested relation on devlink free devlink relation state is normally released from devlunregister, which calls devlinkrelput. This misses devlink instances that get a nested relation before registration and then fa...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: validate skb length in MCC handlers The RFCOMM MCC handlers cast skb-data to protocol-specific structs without validating skb-len first. A malicious remote device can send truncated MCC frames and trigger...

DEBIAN-CVE-2026-53253

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: reject short frames before parsing A BNEP peer can send a short BNEP SDU. bneprxframe reads the packet type byte immediately and, for control packets, reads the control opcode and setup UUID-size byte before...

DEBIAN-CVE-2026-53252

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: fix memory leak in error path of hciallocdev Early failures in Bluetooth HCI UART configuration leak SRCU percpu memory.
