Linux Kernel Security Vulnerabilities

The Linux kernel version 5.18 contains security vulnerabilities. These vulnerabilities arise from the failure to return values when PTP is not in use. During the unbinding of drivers, the uninitialized txskbs queue is cleaned up, leading to null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.6 contains a security vulnerability. This vulnerability arises from the mtkethsoc driver, which allocates a dummy netdev after registering the MAC netdev and adds shared NAPIs. This results in a null pointer derefrence when network devices become visible prematurely,...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.15 contains a security vulnerability. This vulnerability stems from the mctpadddev function, which links the new mctpdev to dev-mctpptr before assigning the value to mdev-dev. When a reader accesses the device during this period, it may dereference a netdevice pointer...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.18 contains a security vulnerability. This vulnerability stems from the s390/cio subsystem, where the ccwdevicegetutilstr function does not check the return value of chpidtochp, which may lead to null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 2.6.33 contains security vulnerabilities. These vulnerabilities arise from the failure to restore the TTYIOERROR flag when the ttyport is activated. This can lead to I/O attempts when the port has disappeared or during power failures. When the TTY ioctl competes with...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference through the ValidateResponse process when a response header is declared with content instead of schema. An attacker can cause a process crash by sending a request to an affected endpoint, resulting in a nil...

CVE-2026-111710

Netcore NR256CN through 1.5.140116 contains a NULL pointer dereference vulnerability in the Boa web server's userauth function that allows unauthenticated attackers to crash the server via a malformed Authorization header. Attackers can send a Basic Authorization value lacking a colon, such as on...
