The function fs_read_glyphs() in src/fc/fserve.c indexes the encoding[] array using num_chars from the FS_QueryXBitmaps16 reply, but that array was allocated based on num_extents from the separate FS_QueryXExtents16 reply—two fi...

CVE-2026-61908

A flaw was found in cyrus-imapd. An authenticated user could exploit this vulnerability by attempting to download a specially crafted JMAP JSON Meta Application Protocol blob ID. This action could lead to reading beyond the intended memory boundary, potentially exposing sensitive information from...

vim: Vim: Denial of Service via crafted spell file

A flaw was found in Vim, an open-source command-line text editor. A remote attacker could exploit this vulnerability by convincing a user to load a specially crafted spell file. This malicious file can trigger a stack out-of-bounds write, which corrupts the editor's memory and causes it to crash...

vim: Vim: Information disclosure and denial of service via crafted Unicode characters in terminal emulator

A flaw was found in Vim. A remote attacker could exploit a heap-based buffer overflow and an out-of-bounds read vulnerability in Vim's terminal emulator. This occurs when processing specially crafted Unicode supplementary plane characters, potentially leading to information disclosure and denial ...

vim: Vim: Denial of Service via out-of-bounds write in terminal handling

A flaw was found in Vim, an open-source command-line text editor. This vulnerability allows a program displaying output in a Vim terminal window to trigger an out-of-bounds write by sending a specific byte sequence. This can lead to a crash of the Vim application, resulting in a Denial of Service...

vim: Vim: Denial of Service via out-of-bounds write in spell sound-folding

An out-of-bounds write vulnerability in Vim's spellsoundfoldsal function allows an attacker to corrupt memory and crash the editor Denial of Service by supplying a specially crafted word during spell sound-folding...

CVE-2026-79516

A flaw was found in nothings stb. An out-of-bounds read vulnerability exists in the stbspvsnprintf function. A local attacker could exploit this by sending a specially crafted input. This could lead to a Denial of Service DoS, making the affected system unavailable. Mitigation Mitigation for this...

CVE-2026-79515

A flaw was found in the stb component. An out-of-bounds read vulnerability in the stbttGetGlyphShape function allows a remote attacker to cause a Denial of Service DoS by sending a specially crafted TrueType Font TTF file. This can lead to the affected application becoming unresponsive or crashin...

kernel: sctp: diag: reject stale associations in dump_one path

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP diagnostics. When performing a socket diagnostic sockdiag lookup, the system may attempt to access memory related to an SCTP association that has already been freed. This can lead to an out-of-bounds read from...

kernel: netfilter: nf_log: validate MAC header was set before dumping it

A flaw was found in the Linux kernel's netfilter logging component. This vulnerability occurs because the system does not properly check if a network packet's Media Access Control MAC header is valid before attempting to log it. A local attacker could send a specially crafted network packet,...

httpd: mod_proxy_ajp: off-by-one out-of-bounds reads in AJP getter functions

A flaw was found in the modproxyajp module of httpd. When processing AJP Apache JServ Protocol messages, the AJP getter functions attempt to read data beyond the allocated buffer size, allowing an attacker or a malformed request to cause an out-of-bounds read. This issue leads to a denial of...

httpd: Apache HTTP Server: Out-of-bounds Read in mod_headers and mod_mime

A flaw was found in Apache HTTP Server. An out-of-bounds read vulnerability exists when modheaders and modmime are used with multiple response languages. This could allow a remote attacker to disclose sensitive information from memory or cause a denial of service...

kernel: sctp: diag: reject stale associations in dump_one path

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP diagnostics. When performing a socket diagnostic sockdiag lookup, the system may attempt to access memory related to an SCTP association that has already been freed. This can lead to an out-of-bounds read from...

kernel: sctp: fix auth_hmacs array size in struct sctp_cookie

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An incorrect array size calculation for the authhmacs field within the sctpcookie structure could lead to a buffer overflow. During the initialization of an SCTP association, if four HMAC identifiers...

kernel: netfilter: nf_log: validate MAC header was set before dumping it

A flaw was found in the Linux kernel's netfilter logging component. This vulnerability occurs because the system does not properly check if a network packet's Media Access Control MAC header is valid before attempting to log it. A local attacker could send a specially crafted network packet,...

kernel: sctp: validate cached peer INIT chunk length in COOKIE_ECHO processing

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation.
