The vulnerability in the implementation of the J1939 network protocol of the Linux operating system allows a perpetrator to gain access to protected information or compromise data integrity.

The vulnerability in the implementation of the J1939 network protocol in Linux operating systems relates to the reutilization of memory previously freed in the j1939netdevstart function within the net/can/j1939/main.c module. This occurs due to concurrent access to ndev-mlpriv-j1939priv race...

The vulnerability of the iopt_unmap_iova_range() function in the drivers/iommu/iommufd/io_pagetable.c file of the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the ioptunmapiovarange function in the drivers/iommu/iommufd/iopagetable.c file of the Linux kernel is related to the use of previously freed memory. Exploiting this vulnerability could allow an attacker to trigger a service failure...

Kernel: NULL pointer dereference problem in sctp_sched_dequeue_common

A NULL pointer dereference issue was found in the SCTP network protocol in net/sctp/streamsched.c in the Linux kernel. If streamin allocation fails, streamout is freed, which would be accessed further. This flaw allows a local user to crash the system or potentially cause a denial of service...

kernel: use-after-free caused by invalid pointer hostname in fs/cifs/connect.c

A use-after-free flaw was found in reconnsetipaddrfromhostname in fs/cifs/connect.c in the Linux kernel. The issue occurs when it forgets to set the free pointer server-hostname to NULL, leading to an invalid pointer request...
