Linux I2C Buffer Overflow DoS

The vulnerability of the amdispdwi2cplatprobe function in the drivers/i2c/busses/i2c-designware-amdisp.c driver for the I2C hardware interface of the Linux operating system is related to synchronization errors when using shared resources “Race Conditions”. Exploiting this vulnerability could allo...

Linux kernel I2C driver Heap Buffer Overflow DoS

The vulnerability of the i2cdevattachadapter function in the drivers/i2c/i2c-dev.c file of the Linux I2C driver module is related to the pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-64275

A flaw was found in the Linux kernel's Elan I2C touchpad driver. This vulnerability occurs when the driver receives invalid zero values for touchpad dimensions from device firmware or the device tree, or when a calculated width is too small. A local attacker with control over device input or a...

CVE-2026-64236

A flaw was found in the i2c davinci driver of the Linux kernel. When the 'clock-frequency' property is missing from the device tree, the driver's fallback mechanism can lead to a division-by-zero error. This vulnerability can be triggered by a local attacker providing a malformed device tree,...

USN-8574-3: Linux kernel vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

USN-8618-1: Linux kernel vulnerabilities

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...
