kernel: ipv6: Fix an uninit variable access bug in __ip6_make_skb()

A flaw was identified in the Linux kernel’s IPv6 networking code in the function ip6makeskb. Under certain conditions—such as when using raw IPv6 sockets and processing ICMPv6 headers—the code may access an uninitialized variable because the expected header data is not guaranteed to reside in the...

kernel: net: qrtr: Fix an uninit variable access bug in qrtr_tx_resume()

An uninitialized memory access flaw was found in the Linux kernel's QRTR Qualcomm IPC Router protocol in the transmit resume handling. When processing RESUMETX messages, if the packet size is smaller than the expected control structure, the qrtrtxresume function reads uninitialized memory from th...

FreeBSD : p7zip -- usage of uninitialized memory (942fff11-5ac4-11ec-89ea-c85b76ce9b5a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 942fff11-5ac4-11ec-89ea-c85b76ce9b5a advisory. - Incorrect initialization logic of RAR decoder objects in 7-Zip 18.03 and before can lead to usage of...

SUSE CVE-2020-10774

A memory disclosure flaw was found in the Linux kernel's versions before 4.18.0-193.el8 in the sysctl subsystem when reading the /proc/sys/kernel/rhfeatures file. This flaw allows a local user to read uninitialized values from the kernel memory. The highest threat from this vulnerability is to...

CVE-2023-45663 Disclosure of uninitialized memory in stbi__tga_load in stb_image

stbimage is a single file MIT licensed library for processing images. The stbigetn function reads a specified number of bytes from context typically a file into the specified buffer. In case the file stream points to the end, it returns zero. There are two places where its return value is not...
