CVE-2021-47110

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

x86/kvm: Disable kvmclock on all CPUs on shutdown

Currenly, we disable kvmclock from machine_shutdown() hook and this only happens for boot CPU. We need to disable it for all CPUs to guard against memory corruption e.g. on restore from hibernate.

Note, writing '0' to kvmclock MSR doesn't clear memory location, it just prevents hypervisor from updating the location so for the short while after write and while CPU is still alive, the clock remains usable and correct so we don't need to switch to some other clocksource.(CVE-2021-47110)

In the Linux kernel, the following vulnerability has been resolved:

i40e: Fix NULL ptr dereference on VSI filter sync

Remove the reason of null pointer dereference in sync VSI filters. Added new I40E_VSI_RELEASING flag to signalize deleting and releasing of VSI resources to sync this thread with sync filters subtask. Without this patch it is possible to start update the VSI filter list after VSI is removed, that's causing a kernel oops.(CVE-2021-47184)

In the Linux kernel, the following vulnerability has been resolved:

erofs: fix pcluster use-after-free on UP platforms

During stress testing with CONFIG_SMP disabled, KASAN reports as below:

The root cause is that erofs_workgroup_unfreeze() doesn't reset to orig_val thus it causes a race that the pcluster reuses unexpectedly before freeing.

Since UP platforms are quite rare now, such path becomes unnecessary. Let's drop such specific-designed path directly instead.(CVE-2022-48674)

In the Linux kernel, the following vulnerability has been resolved:

hwrng: core - Fix page fault dead lock on mmap-ed hwrng

There is a dead-lock in the hwrng device read path. This triggers when the user reads from /dev/hwrng into memory also mmap-ed from /dev/hwrng. The resulting page fault triggers a recursive read which then dead-locks.

Fix this by using a stack buffer when calling copy_to_user.(CVE-2023-52615)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: disallow timeout for anonymous sets

Never used from userspace, disallow these parameters.(CVE-2023-52620)

In the Linux kernel, the following vulnerability has been resolved:

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

tun: avoid double free in tun_free_netdev

Avoid double free in tun_free_netdev() by moving the dev->tstats and tun->security allocs to a new ndo_init routine (tun_net_init()) that will be called by register_netdevice(). ndo_init is paired with the desctructor (tun_free_netdev()), so if there's an error in register_netdevice() the destructor will handle the frees.
