CVE-2023-52601

In the Linux kernel, the following vulnerability has been resolved: jfs: fix array-index-out-of-bounds in dbAdjTree Currently there is a bound check missing in the dbAdjTree while accessing the dmt_stree. To add the required check added the bool is_ctl which is required to determine the size as suggest in the following commit. https://lore.kernel.org/linux-kernel-mentees/[email protected]/

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

KVM: x86/mmu: Don't advance iterator after restart due to yielding

After dropping mmu_lock in the TDP MMU, restart the iterator during tdp_iter_next() and do not advance the iterator. Advancing the iterator results in skipping the top-level SPTE and all its children, which is fatal if any of the skipped SPTEs were not visited before yielding.

When zapping all SPTEs, i.e. when min_level == root_level, restarting the iter and then invoking tdp_iter_next() is always fatal if the current gfn has as a valid SPTE, as advancing the iterator results in try_step_side() skipping the current gfn, which wasn't visited before yielding.

Sprinkle WARNs on iter->yielded being true in various helpers that are often used in conjunction with yielding, and tag the helper with __must_check to reduce the probabily of improper usage.

Failing to zap a top-level SPTE manifests in one of two ways. If a valid SPTE is skipped by both kvm_tdp_mmu_zap_all() and kvm_tdp_mmu_put_root(), the shadow page will be leaked and KVM will WARN accordingly.

But with respect to leaking shadow pages, the bug was introduced by yielding before processing the current gfn.

Alternatively, tdp_mmu_iter_cond_resched() could simply fall through, or callers could jump to their "retry" label. The downside of that approach is that tdp_mmu_iter_cond_resched() must be called before anything else in the loop, and there's no easy way to enfornce that requirement.

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

net: hso: fix null-ptr-deref during tty device unregistration

Multiple ttys try to claim the same the minor number causing a double unregistration of the same device. The first unregistration succeeds but the next one results in a null-ptr-deref.

The get_free_serial_index() function returns an available minor number but doesn't assign it immediately. The assignment is done by the caller later. But before this assignment, calls to get_free_serial_index() would return the same minor number.

Fix this by modifying get_free_serial_index to assign the minor number immediately after one is found to be and rename it to obtain_minor() to better reflect what it does. Similary, rename set_serial_by_index() to release_minor() and modify it to free up the minor number of the given hso_serial. Every obtain_minor() should have corresponding release_minor() call.(CVE-2021-46904)

apparmor: avoid crash when parsed profile name is empty

When processing a packed profile in unpack_profile() described like

"profile :ns::samba-dcerpcd /usr/lib*/samba/{,samba/}samba-dcerpcd {...}"

a string ":samba-dcerpcd" is unpacked as a fully-qualified name and then passed to aa_splitn_fqname().

aa_splitn_fqname() treats ":samba-dcerpcd" as only containing a namespace. Thus it returns NULL for tmpname, meanwhile tmpns is non-NULL. Later aa_alloc_profile() crashes as the new profile name is NULL now.

It seems such behaviour of aa_splitn_fqname() is expected and checked in other places where it is called (e.g. aa_remove_profiles). Well, there is an explicit comment "a ns name without a following profile is allowed" inside.

AFAICS, nothing can prevent unpacked "name" to be in form like ":samba-dcerpcd" - it is passed from userspace.

Deny the whole profile set replacement in such case and inform user with EPROTO and an explaining message.

serial: imx: fix tx statemachine deadlock

When using the serial port as RS485 port, the tx statemachine is used to control the RTS pin to drive the RS485 transceiver TX_EN pin. When the TTY port is closed in the middle of a transmission (for instance during userland application crash), imx_uart_shutdown disables the interface and disables the Transmission Complete interrupt. afer that, imx_uart_stop_tx bails on an incomplete transmission, to be retriggered by the TC interrupt. This interrupt is disabled and therefore the tx statemachine never transitions out of SEND. The statemachine is in deadlock now, and the TX_EN remains…

In the Linux kernel, the following vulnerability has been resolved: jfs: fix array-index-out-of-bounds in dbAdjTree Currently there is a bound check missing in the dbAdjTree while accessing the dmt_stree. To add the required check added the bool is_ctl which is required to determine the size as suggest in the following commit. https://lore.kernel.org/linux-kernel-mentees/[email protected]/

The SUSE Linux Enterprise 15 SP5 RT kernel was updated to receive various security bugfixes.

NOTE: This update has been retracted due to a bug in the BHI CPU sidechannel mitigation, which led to incorrect selection of other CPU mitigations.

The following security bugs were fixed:

• CVE-2021-46925: Fixed kernel panic caused by race of smc_sock (bsc#1220466).
• CVE-2021-46926: Fixed bug when detecting controllers in ALSA/hda/intel-sdw-acpi (bsc#1220478).
