Oj: Use-After-Free in Oj::Parser SAJ Long Key Callback

Summary Oj::Parser in SAJ mode does not protect cached object keys ≥ 35 bytes from garbage collection. A Ruby callback that triggers GC inside hashend can cause the key string to be reclaimed while the C parser still holds a pointer to it. The subsequent access to the freed string VALUE results i...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the Oj::Parser when operating in SAJ mode with object keys of 35 bytes or longer. An attacker can cause a segmentation fault by triggering garbage collection within a callback, leading to use of a freed memory pointer...

Summary Oj::Parser in SAJ mode does not protect cached object keys ≥ 35 bytes from garbage collection. A Ruby callback that triggers GC inside hashend can cause the key string to be reclaimed while the C parser still holds a pointer to it. The subsequent access to the freed string VALUE results i...

Oj: Use-After-Free in Oj::Parser array_class/hash_class GC Marking

Summary Oj::Parser in usual mode does not mark arrayclass and hashclass references during garbage collection. If GC runs after the class is assigned but before a parse, the class object is reclaimed, leaving the parser holding a dangling VALUE. The subsequent parse call dereferences the freed...

In the Linux kernel, the following vulnerability has been resolved: x86/EFI: Fixed handling of graceful page faults after changes to the FPU softirq. Since commit d02198550423 “x86/FPU: Improved crypto performance by making the kernel-mode FPU reliably usable in softirqs”, the kernelfpubegin...

PT-2026-51087

Name of the Vulnerable Software and Affected Versions Oj versions prior to 3.17.2 Description Oj::Parser in usual mode fails to mark array class and hash class references during garbage collection GC, resulting in a Use-After-Free condition. If the GC executes after the class is assigned but befo...

OSEC-2026-04 Bigarray.reshape integer overflow

The function camlbareshape, part of the OCaml runtime in runtime/bigarray.c, had a missing check for integer overflow when computing the size to be allocated. This leads to a segmentation fault. Any application using Bigarray.reshape or reshapeN with untrusted and unchecked input can result in a...

Siemens RUGGEDCOM RST2428P Improper Input Validation (CVE-2025-39913)

Siemens RUGGEDCOM RST2428P Improper Input Validation (CVE-2026-23032)

In the Linux kernel, the following vulnerability has been resolved: nullblk: fix kmemleak by releasing references to fault configfs items When CONFIGBLKDEVNULLBLKFAULTINJECTION is enabled, the null-blk driver sets up fault injection support by creating the timeoutinject, requeueinject, and...

kernel: md/bitmap: fix GPF in write_page caused by resize race

A flaw was found in the Linux kernel's md/bitmap component. This vulnerability involves a use-after-free race condition that occurs during array resize operations. When the bitmapdaemonwork and bitmapresize functions execute concurrently, they can access memory pages that have already been freed...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...
