In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: fix data-race in ipv6_mc_down / mld_ifc_work
idev->mc_ifc_count can be written over without proper locking.
Originally found by syzbot [1], fix this issue by encapsulating calls
to mld_ifc_stop_work() (and mld_gq_stop_work() for good measure) with
mutex_lock() and mutex_unlock() accordingly as these functions
should only be called with mc_lock per their declarations.

Title: Linux kernel (ARM laptop) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel
did not properly validate H2C PDU data, leading to a null pointer
dereference vulnerability. A remote attacker could use this to cause a
denial of service (system crash). (CVE-2023-6356, CVE-2023-6535,
CVE-2023-6536)
It was discovered that the Intel Data Streaming and Intel Analytics
Accelerator drivers in the Linux kernel allowed direct access to the
devices for unprivileged users and virtual machines. A local attacker could
use this to cause a denial of service. (CVE-2024-21823)

Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel
did not properly validate certain data structure fields when parsing lease

In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: fix data-race in ipv6_mc_down / mld_ifc_work
idev->mc_ifc_count can be written over without proper locking.
Originally found by syzbot [1], fix this issue by encapsulating calls
to mld_ifc_stop_work() (and mld_gq_stop_work() for good measure) with
mutex_lock() and mutex_unlock() accordingly as these functions
should only be called with mc_lock per their declarations.
