CVE-2026-98753 tty: tty_port: restore TTY_IO_ERROR on activation failure

In the Linux kernel, the following vulnerability has been resolved: tty: ttyport: restore TTYIOERROR on activation failure Make sure to restore the TTYIOERROR flag if activation fails to prevent I/O attempts on a port that is gone or powered down. This specifically avoids issues like kernel panic...

CVE-2026-98752

The Linux kernel contains a race condition in the tty_port_tty_vhangup() function. This issue occurs when the function races with another hangup, potentially returning before the port is fully shut down. This flaw can lead to use-after-free and NULL-pointer dereferences during racing ioctls (incl...

CVE-2026-98747

The Linux kernel contains a NULL pointer dereference vulnerability in the serial_core_unregister_port() function. The issue occurs because port->port_dev is NULL when no port device is installed—either because it was cleared during teardown or never set due to a registration failure in serial_...

CVE-2026-98740 EDAC/altera: Drop __init from ECC setup paths for re-probe safety

In the Linux kernel, the following vulnerability has been resolved: EDAC/altera: Drop init from ECC setup paths for re-probe safety Sashiko reports: "Does suppressing sysfs unbinding fully prevent the execution of freed init memory? If altrsysmgrregmaplookupbyphandle returns -EPROBEDEFER, the pro...

CVE-2026-98740

The Linux kernel contains a vulnerability where several a10 EDAC .setup callbacks (including sdmmc, ethernet, nand, dma, usb, and qspi) and their helpers were incorrectly marked with init . This allows for potential dereferencing of freed memory if a probe is deferred via -EPROBE_DEFER or trigge...

CVE-2026-98717

The Linux kernel KVM component is vulnerable to a NULL pointer dereference within the x86/mmu shadow page table walking logic. The issue occurs when a race condition exists between memslot creation and a stage-2 page fault (EPT violation or #NPF) from L2. If the root is a "dummy" root—where the t...
