CVE-2026-52948

A flaw was found in the Linux kernel's I2C Inter-Integrated Circuit subsystem. A malicious local user can exploit an integer overflow vulnerability in the I2CTIMEOUT ioctl. By providing a large timeout value, the multiplication by 10 causes an overflow, leading to a truncated value. This results ...

SUSE CVE-2026-52948

In the Linux kernel, the following vulnerability has been resolved: i2c: dev: prevent integer overflow in I2CTIMEOUT ioctl While fuzzing with Syzkaller, a persistent scheduletimeout: wrong timeout value warning was observed, accompanied by SMBus controller state machine corruption. The I2CTIMEOUT...

CVE-2026-46044

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI SSIF SMBus System Interface driver. If an error occurs after a kernel thread kthread is created but before the main IPMI code initializes the SSIF interface, the kthread may not be properly stopped. This could...

CVE-2026-43221

A flaw was found in the Linux kernel's Intelligent Platform Management Bus IPMB component. The IPMB event handler fails to initialize read bytes, which can lead to an uninitialized value being returned during an I2C Inter-Integrated Circuit read operation. This could allow a local attacker to...

CVE-2026-43221

In the Linux kernel, the following vulnerability has been resolved: ipmi: ipmb: initialise event handler read bytes IPMB doesn't use i2c reads, but the handler needs to set a value. Otherwise an i2c read will return an uninitialised value from the bus driver...

CVE-2025-39928

CVE-2025-39928 affects the Linux kernel RTL9300 I2C driver. The vulnerability arises from not validating the transfer length in rtl9300_i2c_config_xfer, allowing a data length of 0 to underflow and be treated as 16 due to (len - 1) & 0xf, which can trigger a 16-byte write and potentially soft-bri...
