CVE-2026-65610

nnn stores homelen variable as uchart, which can only represent values in the range 0-255. An attacker who can influence the victim's execution environment can provide an arbitrary HOME path with length that is truncated to 0. The expression homelen - 1 is promoted to signed int and becomes -1 an...

gstreamer1-plugins-good: gstreamer: unsigned integer underflow in avidemux FUJIFILM strd parsing leading to out-of-bounds read/write

A flaw was found in GStreamer gst-plugins-good avidemux. When parsing FUJIFILM metadata in an AVI strd chunk, gstavidemuxparsestrd decrements a remaining-length counter by fixed offsets 98 and 10 bytes without verifying sufficient data remains. For crafted strd payloads of exactly 106 or 107 byte...

USN-8649-1 libheif vulnerabilities

It was discovered that libheif had an integer underflow in the Fraction constructor when a clap transform was applied twice. An attacker could possibly use this issue to cause libheif to crash, resulting in a denial of service. CVE-2026-62289 It was discovered that libheif had an out-of-bounds re...

BIT-POSTGRESQL-2026-16241 PostgreSQL ECPG integer underflow can crash the client

Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of service against the ECPG client via sending a bytea value lacking the mandatory prefix. The client overwrites a huge memory region with bytes outside attacker knowledge or control. This...

CVE-2026-72326

A flaw was found in the Linux kernel's CAKE Common Applications Kept Enhanced packet scheduler. This vulnerability arises from the incorrect handling of signed overhead values, which can lead to an integer underflow during packet length calculations. A negative effective length can then wrap to a...

CVE-2026-72225

A flaw was found in the Linux kernel's jbd2 journaling layer. An integer underflow vulnerability in the jbd2journalinitializefastcommit function occurs when validating journal capacity. This underflow can corrupt critical journal metadata, such as jlast, jfcfirst, and jfree, leading to a journal...

CVE-2026-49419

The FreeBSD operating system (versions 15.0 and later ) is vulnerable to a prison reference count underflow in the kern_jail_set() and kern_jail_get() functions. When the JAIL_AT_DESC flag is used, the system incorrectly releases a reference to the caller's current prison before searching for the...

PT-2026-78597

Name of the Vulnerable Software and Affected Versions IBM AIX versions 7.2 and 7.3 IBM PowerVM VIOS version 4.1 Description A remote attacker could cause a denial of service due to an integer underflow, which occurs when an arithmetic operation results in a value smaller than the minimum...

CVE-2026-49419: Improper Update of Reference Count

When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...

CVE-2026-58087: Integer Underflow (Wrap or Wraparound)

The GETALL and SETALL commands in semctl2 recorded the number of semaphores in the target set, dropped the lock protecting the set, allocated a buffer sized for that count, and reacquired the lock. A sequence-number check was used to verify that the set had not been replaced in the interim, but t...
