PT-2026-65346

The Avro array and map decoders loop over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is 64-bit on amd64 and arm64 targets. A producer can declare a block of up to...

CVE-2026-64280

In the Linux kernel, the following vulnerability has been resolved: fpga: dfl-afu: validate DMA mapping length in afudmamapregion afuioctldmamap accepts a 64-bit length from userspace via DFLFPGAPORTDMAMAP ioctl without an upper bound check. The value is passed to afudmapinpages where npages is...

CVE-2026-43905

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, jpeg2000input.cpp:395 computes buffer size as const int bufsize = w h ch bufferbpp using signed 32-bit arithmetic. When the product...

CVE-2026-44636 libsixel: integer overflow in encoder

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. From to 1.8.7-r1, signed integer overflow in sixelencodehighcolor's allocation size calculation can lead to a heap buffer overflow. The public sixelencode entry point validates only that width and height are greater th...

EUVD-2026-29172

jq is a command-line JSON processor. In 1.8.1 and earlier, when decNumberFromString is given a number literal of INTMAX-1 2147483646 digits, the D2U macro overflows during signed-int arithmetic. The wrapped negative value bypasses the heap-allocation size check, causes the function to use a 30-by...

CVE-2026-37555

An issue was discovered in libsndfile 1.2.2 IMA ADPCM codec. The AIFF code path line 241 was fixed with sfcountt cast, but the WAV code path line 235 and close path line 167 were not. When samplesperblock int blocks int exceeds INTMAX, the 32-bit multiplication overflows before being assigned to...

Unity Linux 20.1070e Security Update: kernel (UTSA-2026-001763)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001763 advisory. copyparams in drivers/md/dm-ioctl.c in the Linux kernel through 6.7.1 can attempt to allocate more than INTMAX bytes, and crash, because of a missing...

CVE-2023-54251 net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX.

In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: Limit TCATAPRIOATTRSCHEDCYCLETIME to INTMAX. syzkaller found zero division error 0 in divs64rem called from getcycletimeelapsed, where sched-cycletime is the divisor. We have tests in parsetaprioschedule so tha...

Linux Distros Unpatched Vulnerability : CVE-2023-53624

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net/sched: schfq: fix integer overflow of credit if schfq is configured with initial quantum having values greater than INTMAX, the first assignment of credit...

CVE-2023-53624

In the Linux kernel, the following vulnerability has been resolved: net/sched: schfq: fix integer overflow of "credit" if schfq is configured with "initial quantum" having values greater than INTMAX, the first assignment of "credit" does signed integer overflow to a very negative value. In this...

CVE-2023-53624

The CVE-2023-53624 issue affects the Linux kernel’s net/sched implementation, specifically sch_fq. It arises when the initial quantum (configured for sch_fq) exceeds INT_MAX, causing the first assignment to the credit field to overflow to a very negative value. This can trigger a CPU soft-lockup ...
