Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via missing decompression bomb checks in the seek methods of DcxImagePlugin, MicImagePlugin, and MpoImagePlugin. When a multi-frame image file DCX, MIC, or MPO format is opened and seeked to a...

Buffer Over-read

Overview Affected versions of this package are vulnerable to Buffer Over-read via the decodeStrip and decodeTile functions in src/libImaging/TiffDecode.c, where the TIFF strip and tile decode buffers are reallocated without zeroing the region beyond previously decoded data. When a codec such as...

Improper Handling of Highly Compressed Data (Data Amplification)

Overview Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification via the MSP image decoder in src/PIL/MspImagePlugin.py, where a malicious MSP file with run-length encoded rows can cause the decoder to expand more data than the image widt...

Inefficient Algorithmic Complexity

Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via repeated string concatenation in the seek function of src/PIL/GifImagePlugin.py when parsing GIF comment extension blocks. An attacker can supply a GIF file containing many comment blocks, causing...

Use of Uninitialized Resource

Overview Affected versions of this package are vulnerable to Use of Uninitialized Resource via the TIFF strip and tile decoder in src/libImaging/TiffDecode.c, when decoding TIFF images using codecs such as JPEG or Group 4 that successfully decode fewer rows than the declared strip or tile length...

SUSE CVE-2026-98668

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Ensure bounce buffer used for unaligned case is zeroed. iiopushtobufferswithtsunaligned leaks uninitialized heap memory to userspace if the data passed in is not a multiple of 8 bytes and the timestamp is enabled...

CVE-2026-98545

A flaw was found in the Linux kernel's libata SCSI subsystem. When processing ATA pass-through commands to an ATAPI storage device, the kernel fails to properly validate the length byte returned in the device's sense response buffer. A malicious or faulty device can exploit this issue to trigger...

CVE-2026-112898

A flaw was found in Pillow. When processing an image with an empty palette during color quantization, internal stack memory is left uninitialized and emitted into the output image data. An attacker who supplies a crafted palette image can exploit this vulnerability to read uninitialized memory...

CVE-2026-98541

A flaw was found in the Linux kernel's Foo-over-UDP FOU networking subsystem. When configuring a direct encapsulation tunnel without specifying the required network protocol attribute, the kernel permits tunnel socket creation with an uninitialized protocol value. Consequently, incoming network...

CVE-2026-98540

A flaw was found in the Linux kernel's function probe fprobe tracing component. This vulnerability can result in a Denial of Service DoS due to improper memory initialization. When tracing kernel functions, unused shadow stack space is left uncleared, causing return routines to parse leftover dat...

CVE-2026-112897

A flaw was found in Pillow. This flaw can lead to information disclosure when handling compressed Tagged Image File Format TIFF images. During incomplete decoding of image data, uninitialized buffer memory is not cleared before being converted into pixel rows. A remote attacker can exploit this...

CVE-2026-77684

The Bluetooth Classic Hands-Free Profile HF role in subsys/bluetooth/host/classic/hfphf.c does not release the AT command buffers that are still queued on hf-txpending when the RFCOMM DLC goes down. hfphfdisconnected only cancelled the work items and cleared hf-acl, and no other code path ever...

CVE-2026-112893

A flaw was found in Pillow. When rendering text using FreeType with an active stroke width, a failure during glyph loading can cause the library to free an uninitialized or stale memory pointer. A remote attacker could exploit this vulnerability by supplying a malformed font to an application tha...

CVE-2026-112397

A flaw was found in Pillow. A remote attacker can cause a Denial of Service DoS by supplying a specially crafted image with a width of zero to an application performing morphology operations. Because Pillow fails to validate zero-width image geometry during these operations, it attempts an...

DEBIAN-CVE-2026-112898

Pillow is a Python imaging library. From 9.1.0 until 13.0.0, Pillow can disclose uninitialized stack memory when Image.quantize uses an empty palette. ImagingPaletteCacheUpdate leaves a local cache array uninitialized when the palette has zero entries, and the conversion path emits those bytes as...

CVE-2026-112898

Pillow is a Python imaging library. From 9.1.0 until 13.0.0, Pillow can disclose uninitialized stack memory when Image.quantize uses an empty palette. ImagingPaletteCacheUpdate leaves a local cache array uninitialized when the palette has zero entries, and the conversion path emits those bytes as...

DEBIAN-CVE-2026-112896

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's TIFF encoder can read beyond a ColorMap buffer when retained TIFF metadata has a plane size inconsistent with BitsPerSample. A small TIFF can be opened normally and then retain a crafted ColorMap that is reused when the image is saved...

DEBIAN-CVE-2026-112893

Pillow is a Python imaging library. From 10.0.0 until 13.0.0, Pillow can free an invalid glyph pointer during FreeType rendering with an active stroker. If FTLoadGlyph fails, cleanup may call FTDoneGlyph on an uninitialized or stale glyph variable. An attacker can supply a malformed font as...
