Integrity: None
Availability: Low

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 5 Jun 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 31 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

This update for 7zip fixes the following issues Update to 26.01: - CVE-2026-48092: Information disclosure in 32-bit builds due to heap memory disclosure (bsc#1267858). - CVE-2026-48095: Heap buffer overflow via NTFS compressed stream buffer under-allocation (bsc#1267421). - CVE-2026-48101: Information Disclosure via uninitialized memory in UEFI capsule parser (bsc#1267859). - CVE-2026-48102: Information disclosure and denial of service via crafted UDF image (bsc#1267860). - CVE-2026-48103: off-by-one heap out-of-bounds read (bsc#1267861). - CVE-2026-48104: Uninitialized heap read in SquashFS archive handler (bsc#1267862). - CVE-2026-48111: off-by-one out-of-bounds read in ParseDepedencyExpression function (bsc#1267863). - CVE-2026-48112: heap out-of-bounds read in BSD SYMDEF parser (bsc#1267864). Changes: * linux version of 7-Zip can use huge pages (2 MB pages). It can increase compression speed for 10% for 7z/xz/LZMA/LZMA2 compression. * new -spo[d|c|r] switch specifies the path generation mode for the output directory for archive extraction. The output directory path is generated from the path specified in the -o{dir_path} switch and the name of the archive being unpacked. -spod : for Linux/Posix/macOS: -o{dir_path} specifies the direct path to the output directory. The asterisk (*) character in {dir_path} will not be replaced by the archive name. -spoc : 7-Zip will concatenate the path specified in -o{dir_path} with the archive name to form the final path to the output directory. -spor : 7-Zip will replace asterisk (*) character in the path specified in the -o{dir_path} with the archive name. This is the default option. * some bugs were fixed. - Update to 26.00: * improved code for ZIP, CPIO, RAR, UFD, QCOW, Compound. * 7-Zip File Manager: improved sorting order of the file list. It uses file name as secondary sorting key.: * 7-Zip File Manager: improved Benchmark to support systems with more than 64 CPU threads. * bug fixed: 7-Zip could not correctly extract TAR archives containing sparse files
