libxml2: libxml2: Data integrity issues due to integer overflow in write callbacks

An integer overflow in the libxml2 xmlIO module occurs when data backlogs exceed maximum integer limits. This flaw passes negative length values to downstream write callbacks, creating an unsafe state that can lead to data corruption or compromise application confidentiality and integrity...

CVE-2026-86143

In xmlIO in libxml2 before 2.15.4, an inconsistency in xmlOutputWriteCallback and xmlBufUse causes negative lengths to reach write callbacks, aka a lack of a check for integer overflow before calling writecallback. This has security relevance for many types of uses of that length value within a...

AZL-99705 CVE-2026-86143 affecting package libxml2 for versions less than 2.11.5-11

In xmlIO in libxml2 before 2.15.4, an inconsistency in xmlOutputWriteCallback and xmlBufUse causes negative lengths to reach write callbacks, aka a lack of a check for integer overflow before calling writecallback. This has security relevance for many types of uses of that length value within a...

CVE-2026-86143

libxml2 before 2.15.4 has an integer overflow in the xmlIO module. An inconsistency between xmlOutputWriteCallback and xmlBufUse causes negative length values to reach downstream write callbacks when data backlogs exceed maximum integer limits (approximately 2 GiB ). This can lead to data corrupt...

CVE-2026-64336

A flaw was found in the Linux kernel's keyspanpda USB serial driver. An issue with the write callback function allows it to report more data written than was actually provided. This can lead to the system writing data beyond its allocated buffer, resulting in an information leak. A local attacker...

CVE-2026-64336

In the Linux kernel, the following vulnerability has been resolved: USB: serial: keyspanpda: fix information leak The write callback is supposed to return the number of characters accepted or a negative errno. Since the addition of write fifo support the keyspanpda implementation will however...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: uacce: fixed the isolate/sysfs check condition. uacce supports the device isolation feature. If the driver implements the isolateerrthresholdread and isolateerrthresholdwrite callback functions, uacce will now create sysfs...

CVE-2025-8860

CVE-2025-8860 affects QEMU by a flaw in the uefi-vars device: after writing to UEFI_VARS_REG_BUFFER_SIZE, a heap buffer is allocated without zeroing, leaving residual data that can be read later from UEFI_VARS_REG_PIO_BUFFER_TRANSFER, causing information disclosure. Oracle Linux advisories ELSA-2...

CVE-2025-8860 Qemu-kvm: uefi-vars: information disclosure vulnerability in uefi_vars_write callback

A flaw was found in QEMU in the uefi-vars virtual device. When the guest writes to register UEFIVARSREGBUFFERSIZE, the .write callback uefivarswrite is invoked. The function allocates a heap buffer without zeroing the memory, leaving the buffer filled with residual data from prior allocations. Wh...
