SUSE CVE-2026-72047

In the Linux kernel, the following vulnerability has been resolved: ieee802154: ca8210: fix pointer truncation in kfifo on 64-bit ca8210testintdriverwrite and ca8210testintuserread exchange a kmalloc'd buffer pointer through a struct kfifo, but pass a literal '4' as the byte count to...

SUSE CVE-2026-72048

In the Linux kernel, the following vulnerability has been resolved: ieee802154: ca8210: fix casctl leak on spiasync failure ca8210spitransfer allocates casctl with kzallocobjGFPATOMIC and relies entirely on the SPI completion callback ca8210spitransfercomplete to free it. The spiasync API only...

CVE-2026-72048

A flaw was found in the Linux kernel. The ieee802154: ca8210 driver fails to free allocated memory casctl when the spiasync operation encounters an error. Under sustained Serial Peripheral Interface SPI bus contention, this can lead to repeated memory leaks. This continuous resource exhaustion ma...

CVE-2026-72048

Linux kernel: ieee802154 ca8210 driver leaks cas_ctl on spi_async failure due to kzalloc_obj(GFP_ATOMIC) allocation that is only freed in the completion callback. On submission failure, spi_async() does not queue a callback, leaving cas_ctl and embedded spi_message/spi_transfer orphaned. The leak...

CVE-2026-72047

Summary: CVE-2026-72047 affects the Linux kernel, specifically the ieee802154 ca8210 driver. A 64‑bit build flaw occurs when ca8210_test_int_driver_write() and ca8210_test_int_user_read() exchange a kmalloc’d buffer pointer through a struct kfifo and pass a literal 4 as the byte count to kfifo_in...

PT-2026-72237

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak occurs in the ieee802154 driver for the ca8210 device. The function ca8210 spi transfer allocates a cas ctl object using kzalloc objGFP ATOMIC and expects the ca8210 spi...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the ca8210 driver not properly validating maclen, which could result in a buffer overflow...
