CVE-2022-48693

CVE-2022-48693 affects the Linux kernel’s brcmstb PM subsystem (soc: brcmstb: pm-arm). The two leak bugs are in brcmstb_pm_probe() and include: (1) missing of_node_put() when for_each__matching_node() breaks, and (2) missing iounmap() for each iomap in the failure path. Public information in conn...

CVE-2024-27054

A vulnerability was found in the dasdgenericsetonline function in the Linux Kernel's s390 dasd.c driver, where improper reference count handling on error paths can lead to the refcount value being decreased twice, resulting in an incorrect underflow. This issue can lead to system instability...

CVE-2024-27054

The CVE-2024-27054 issue resides in the Linux kernel s390/dasd path where the module refcount could be decremented twice due to manual handling of refcounts after device association. The vulnerability results in an artificial decrease of the module’s refcount on each error path, rather than keepi...
