CVE-2026-91189

The GUIX binary resource loader never checks that a font page's glyph range is well formed. gxpageheaderfirstglyph and gxpageheaderlastglyph are read verbatim from the file and only the upper bound of lastglyph is validated, so a page declaring firstglyph lastglyph makes last - first + 1 underflo...

CVE-2026-91189 GUIX binary resource loader: unvalidated glyph range causes an integer underflow and a heap out-of-bounds write when loading an untrusted font or theme

The GUIX binary resource loader never checks that a font page's glyph range is well formed. gxpageheaderfirstglyph and gxpageheaderlastglyph are read verbatim from the file and only the upper bound of lastglyph is validated, so a page declaring firstglyph lastglyph makes last - first + 1 underflo...

CVE-2026-92449

gxbinrespixelmaptableload in the GUIX binary resource theme loader indexes the pixelmap table with a value read verbatim from the resource file and never bounds it against the table size. A crafted theme drives a write of up to roughly 256 KB past the end of the table. The overflowed buffer is...

CVE-2026-92449 Binary resource loader: unbounded map_id from a theme file causes a heap out-of-bounds write in the GUIX-allocated arena

gxbinrespixelmaptableload in the GUIX binary resource theme loader indexes the pixelmap table with a value read verbatim from the resource file and never bounds it against the table size. A crafted theme drives a write of up to roughly 256 KB past the end of the table. The overflowed buffer is...

CVE-2026-91186

The PNG chunk reader has no notion of chunk ordering. It records whether an IDAT has been seen and whether a tRNS has already supplied transparency, but nothing prevents an IHDR being read a second time. A PNG carries exactly one IHDR and it is the first chunk. A file that places a second one aft...

CVE-2026-91186 PNG decoder: a duplicate IHDR chunk after IDAT resizes the image after allocation, causing a heap out-of-bounds write

The PNG chunk reader has no notion of chunk ordering. It records whether an IDAT has been seen and whether a tRNS has already supplied transparency, but nothing prevents an IHDR being read a second time. A PNG carries exactly one IHDR and it is the first chunk. A file that places a second one aft...

CVE-2026-91041

The FileX filesystem component is vulnerable to an out-of-bounds heap write during log replay when mounting a crafted FAT image with fault tolerance enabled. The vulnerability is caused by the system writing past the destination sector, allowing an attacker to control the position and value of th...

CVE-2026-91041 FileX fault-tolerant log replay writes past the destination sector when mounting a crafted FAT image

Mounting an attacker-controlled FAT image with fault tolerance enabled causes an out-of-bounds heap write during log replay. The write is attacker-positioned and attacker-valued, and on a common embedded memory layout it reaches the FXMEDIA driver callback, giving control of the instruction point...

CVE-2026-93122

A flaw was found in the Linux kernel's USB Audio Class UAC gadget driver. This vulnerability occurs when processing a list of sampling rates, where the driver fails to properly validate the length of the input list. An attacker could provide an overly long list, causing the system to write data...

CVE-2026-93095

A flaw was found in the HFS Plus HFS+ filesystem in the Linux kernel. A local attacker could provide a specially crafted, corrupted HFS+ image that, when processed during a delete key rebuild operation, would cause the system to write past an allocated memory buffer. This out-of-bounds write coul...

CVE-2026-93079

A flaw was found in the Linux kernel's CXL Compute Express Link feature handling. The cxlctlgetfeature function does not properly validate the size of the output buffer against a user-controlled count value. This oversight allows a local attacker to provide a count larger than the allocated buffe...

CVE-2026-93053

A flaw was found in the Linux kernel's speakup component. A local attacker with root privileges could exploit a vulnerability in the keyhelp module by overriding function names in sysfs. This manipulation could cause an out-of-bounds write in the letteroffsets array, potentially leading to system...
