A use after free issue was addressed with improved memory management. This issue is fixed in Safari 17.2, iOS 17.2 and iPadOS 17.2, tvOS 17.2, watchOS 10.2, macOS Sonoma 14.2. Processing maliciously crafted web content may lead to arbitrary code execution...

PT-2026-37846

A flaw was found in how GLib’s GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn’t. As a result, data may be writte...

In the Linux kernel, the following vulnerability has been resolved: reset: gpio: fix double free in resetaddgpioauxdevice error path When auxiliarydeviceadd fails, resetaddgpioauxdevice calls auxiliarydeviceuninitadev. The device release callback resetgpioauxdevicerelease frees adev, but the...

CVE-2026-31787

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

glibc: glibc: Out-of-bounds write via TSIG record processing

A flaw was found in glibc, the GNU C Library. Specifically, deprecated functions responsible for printing TSIG Transaction Signature records fail to properly manage memory buffers. This oversight can lead to an out-of-bounds write when processing specially crafted TSIG records. An attacker could...
