CVE-2026-89622

CVE-2026-89622 is a write use-after-free in the Linux kernel's HID mcp2221 driver . The function mcp_i2c_smbus_read() stores a caller-supplied buffer pointer in mcp->rxbuf but fails to clear it when an I2C/SMBus transfer completes or times out. Once the caller frees the buffer, a delayed or sp...

CVE-2026-89598

CVE-2026-89598 affects the ssd1307fb fbdev driver in the Linux kernel . The root cause is that fbdev damage callbacks may execute from fbcon while printk has disabled preemption, causing the driver to enter a sleeping I2C transfer path from atomic context . The reported consequence is a "scheduli...

CVE-2026-80970

CVE-2026-80970 affects the Linux kernel ALSA FCP USB audio driver. In fcp_ioctl_init(), the response buffer is allocated via kmalloc() without being zeroed. Because the step-0 USB control transfer does not set URB_SHORT_NOT_OK, a short or zero-length data stage is accepted as success, and snd_usb...

CVE-2026-80950

A use-after-free vulnerability exists in the Linux kernel's Renesas I3C driver . The driver uses an asynchronous data-transfer model: it enqueues a transfer struct and waits for completion. If a transfer times out , the waiting thread frees the struct. If an interrupt then fires, the interrupt ha...

SUSE CVE-2026-89044

Netty versions 4.1.133.Final through 4.1.137.Final and 4.2.13.Final through 4.2.17.Final fail to properly validate the final transfer coding in the Transfer-Encoding header, allowing attackers to smuggle requests by using malformed encoding declarations. Attackers can split Transfer-Encoding...

curl: CVE-2026-92387: never-ending loop via server response omission

Hi all, I found a way to make a malicious FTP, IMAP, POP3, or SMTP server defeat libcurl's own transfer timeout entirely and, worse, freeze every other transfer sharing the same multi handle. All it takes is never sending a final control-response line. The bug Curlppstatemach checks the response...
