IBM QRadar 7.5.0 through 7.5.0 UP15 Interim Fix 005 contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data.

IBM QRadar 7.6.0.0 through 7.6.0.1, and 7.5.0 through 7.5.0 UP 15 Interim Fix 005 could allow an authenticated privileged user to execute arbitrary commands with normal user privileges on the system due to improper validation of user supplied input.

IBM QRadar 7.6.0.0 through 7.6.0.1, and 7.5.0 through 7.5.0 UP 15 Interim Fix 005 has an XML External Entity (XXE) injection vulnerability. The vulnerability resides in the parseXmlPayload() function within the event processing pipeline ( q1labscore.jar ). When at least one log source type is configured to use XML-format property autodetection, the system processes XML-formatted syslog events sent to port 514 (UDP/TCP) without authentication.

IBM QRadar 7.5.0 through 7.5.0 UP15 Interim Fix 002 could allow a privileged user to upload a malicious backup archive that could be restored and used to gain access to the underlying operating system.

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

KVM: x86/mmu: Drop/zap existing present SPTE even when creating an MMIO SPTE

When installing an emulated MMIO SPTE, do so after dropping/zapping the existing SPTE (if it's shadow-present). While commit a54aa15c6bda3 was right about it being impossible to convert a shadow-present SPTE to an MMIO SPTE due to a guest write, it failed to account for writes to guest memory that are outside the scope of KVM.

E.g. if host userspace modifies a shadowed gPTE to switch from a memslot to emulted MMIO and then the guest hits a relevant page fault, KVM will install the MMIO SPTE without first zapping the shadow-present SPTE.

XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in stserialstack

XML::Parser versions through 2.45 for Perl could overflow the pre-allocated buffer size cause a heap corruption (double free or corruption) and crashes.

A :utf8 PerlIO layer, parsestream() in Expat.xs could overflow the XML input buffer because Perl's read() returns decoded characters while SvPV() gives back multi-byte UTF-8 bytes that can exceed the pre-allocated buffer size. This can cause heap corruption (double free or corruption) and crashes.

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

scsi: qla2xxx: Fix improper freeing of purex item

In qla2xxxprocesspurlsiocb(), an item is allocated via qla27xxcopymultiplepkt(), which internally calls qla24xxallocpurexitem().

The qla24xxallocpurexitem() function may return a pre-allocated item from a per-adapter pool for small allocations, instead of dynamically allocating memory with kzalloc().

An error handling path in qla2xxxprocesspurlsiocb() incorrectly uses kfree() to release the item. If the item was from the pre-allocated pool, calling kfree() on it is a bug that can lead to memory corruption.

Fix this by using the correct deallocation function, qla24xxfreepurexitem(), which properly handles both dynamically allocated and pre-allocated items.

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

net: qlogic/qede: fix potential out-of-bounds read in qedetpacont() and qedetpaend()

The loops in 'qedetpacont()' and 'qedetpaend()', iterate over 'cqe->lenlist[]' using only a zero-length terminator as the stopping condition. If the terminator was missing or malformed, the loop could run past the end of the fixed-size array.

Add an explicit bound check using ARRAYSIZE() in both loops to prevent a potential out-of-bounds access.

nvme: avoid double free special payload

If a discard request needs to be retried, and that retry may fail before a new special payload is added, a double free will result. Clear the RQFSPECIALLOAD when the request is cleaned.
