PT-2023-8768

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the Linux kernel's handling of uninitialized stack memory. Privileged programs are supposed to be able to read this memory, but before the patch, these accesses...

The vulnerability in the `drm_mode_setcrtc()` function of the `drivers/gpu/drm/drm_crtc.c` file of the Linux operating system’s DRM driver module allows a attacker to influence the integrity and accessibility of information, and execute arbitrary code.

The vulnerability of the drmmodesetcrtc function in the drivers/gpu/drm/drmcrtc.c file of the Linux operating system’s DRM driver module relates to access to uninitialized dynamic memory. Exploiting this vulnerability could allow a attacker to influence the integrity and accessibility of...

kernel: wifi: ath9k: avoid referencing uninit memory in ath9k_wmi_ctrl_rx

A flaw was identified in the Linux kernel’s ath9k wireless driver where the receiver packet handling code did not correctly validate the length of incoming SKBs before accessing subsequent fields expected to be present. In certain malformed packet conditions e.g., pktlen set too small, the driver...

kernel: drm/gud: Fix UBSAN warning

A flaw was found in the GUD Generic USB Display driver in the Linux kernel. Uninitialized iosysmap variables on the stack contain garbage values in their isiomem boolean field. When iosysmapclear checks this field, UBSAN flags it as an invalid boolean value, indicating potential undefined behavio...

kernel: usb: idmouse: fix an uninit-value in idmouse_open

A use of uninitialized memory was found in the Linux kernel's idmouse USB fingerprint reader driver. In idmousecreateimage, when any ftipcommand fails, control jumps to the reset label but leaves bulkinbuffer data uninitialized. The subsequent check for a valid image then dereferences this...

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...

NewStart CGSL MAIN 6.06 : tar Vulnerability (NS-SA-2023-0135)

The remote NewStart CGSL host, running version MAIN 6.06, has tar packages installed that are affected by a vulnerability: - GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has no...

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
