libssh Security Vulnerabilities

libssh is a C development package from the libssh organization for accessing SSH services, which can perform remote commands, file transfers, and also provide a secure transport channel for remote programs. A security vulnerability exists in libssh that stems from a return value that is not...

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: 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: 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: 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...

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...

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...
