Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: BPF: Fixed potential improper pointer dereferencing in bpfsysbpf. The bpfsysbpf helper function allows an eBPF program to load another eBPF program from within the kernel. In this case, the argument union bpfattr pointer along...

OpenEXR Out of Bounds Heap Read due to Bad Pointer Arithmetic in LossyDctDecoder_execute

SummaryThe OpenEXRCore code is vulnerable to a heap-based buffer overflow during a read operation due to bad pointer math when decompressing DWAA-packed scan-line EXR files with a maliciously forged chunk. DetailsIn the LossyDctDecoderexecute function from src/lib/OpenEXRCore/internaldwadecoder.h...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the rxrpckernellookuppeer function in the rxrpc AFS component. This function may return an...

The vulnerability of the do_service_request() function in the drivers/cpufreq/loongson3_cpufreq.c driver module, a Linux kernel frequency scaling support driver, allows a hacker to trigger a service failure.

The vulnerability of the doservicerequest function in the drivers/cpufreq/loongson3cpufreq.c driver, a driver for scaling CPU frequency in Linux operating systems, is related to an attempt to access a non-structured pointer’s child element. Exploiting this vulnerability could allow an attacker to...

CVE-2022-50069

CVE-2022-50069 concerns the Linux kernel BPF subsystem. The root cause is that bpf_sys_bpf() may copy instruction data from a kernel address (via bpfptr_t) without validating it, since copy_from_bpfptr() can dereference in-kernel pointers. This can lead to a use-after-free/invalid dereference in ...

SUSE CVE-2025-4638

A vulnerability exists in the inftrees.c component of the zlib library, which is bundled within the PointCloudLibrary PCL. This issue may allow context-dependent attackers to cause undefined behavior by exploiting improper pointer arithmetic. Since version 1.14.0, PCL by default uses a zlib...

CVE-2021-47337

A vulnerability was found in the Linux kernel's SCSI subsystem. The issue occurs when the system tries to stop an error handler thread that failed to start; if the thread fails to spawn, the kernel may dereference a bad pointer, leading to potential system crash. Mitigation Red Hat has investigat...

CVE-2021-47337

The CVE-2021-47337 issue is in the Linux kernel SCSI core path: when an error arises during scsi_host_alloc() and the error-handling ehandler thread fails to spawn, shost->ehandler may be set to ERR_PTR(-ENOMEM) and scsi_host_dev_release() would call kthread_stop() on a NULL/invalid pointer, r...
