CVE-2026-54058 Pillow: Out-of-bounds read via attacker-controlled row stride on Pillow's mmap path (McIdas AREA files)

Pillow is a Python imaging library. Prior to 12.3.0, when Pillow loads an uncompressed McIdas AREA image from a filename through the mmap raw codec path, attacker-controlled header words can set a row stride smaller than the natural row width, causing pixel access such as Image.tobytes, getpixel,...

CVE-2026-54058

Pillow (Python imaging library) contains CVE-2026-54058, affecting the mmap raw codec path when loading uncompressed McIdas AREA images. Attacker-controlled header words can set a row stride smaller than the natural row width, enabling reads beyond the mapped region and potentially disclosing adj...

The vulnerability of the `tracing_buffers_mmap_close()` function in the kernel/trace/trace.c module, which supports Linux operating system’s kernel tracing functionality, allows a hacker to cause a service failure.

The vulnerability of the tracingbuffersmmapclose function in the kernel/trace/trace.c module, which supports Linux operating system’s kernel tracing mechanism, involves copying buffers without checking the size of the input data a classic buffer overflow attack. Exploiting this vulnerability can...

SUSE CVE-2026-53084

In the Linux kernel, the following vulnerability has been resolved: bpf: return VMA snapshot from taskvma iterator Holding the per-VMA lock across the BPF program body creates a lock ordering problem when helpers acquire locks that depend on mmaplock: vmlock - irwsem - mmaplock - vmlock Snapshot...

kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...

CVE-2026-45258 Multiple vulnerabilities in the sound(4) mmap path

dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length wrapped around and passed the check. The offset was then narrowed from 64 to 32 bits when converted to ...

CVE-2026-45258

The CVE-2026-45258 issue affects FreeBSD sound(4) mmap support. dsp_mmap_single() overflows when validating the requested mapping because offset+length can wrap the size check, and the offset is reduced from 64 to 32 bits for the buffer address, allowing a mapping that extends past the audio buff...

CVE-2026-49417

CVE-2026-49417 is part of two memory-safety issues in FreeBSD’s sound(4) mmap path. The advisories describe: (1) dsp_mmap_single() could overflow when validating a requested mapping, allowing a mapping to extend past the audio buffer into kernel memory (CVE-2026-45258), and (2) the audio buffer b...

CVE-2026-49417 Multiple vulnerabilities in the sound(4) mmap path

Second, the audio buffer backing a mapping could be freed when the device was closed even though the mapping remained valid. The freed memory could then be reused elsewhere while still accessible through the stale mapping. The /dev/dsp device nodes are world-accessible by default. On a system wit...
