Linux: >> Linux Kernel >> 2.1.33 Security Vulnerabilities
A null pointer dereference issue was found in can protocol in net/can/af_can.c in the Linux before Linux. ml_priv may not be initialized in the receive path of CAN frames. A local user could use this flaw to crash the system or potentially cause a denial of service.

A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault handler. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel.

A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28.

A use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system due to a race problem. This vulnerability could even lead to a kernel information leak problem.
