| Use-after-free in PQC hybrid key-share handling. This is an incomplete-fix follow-up to CVE-2026-5460 (released in 5.9.1): a malicious TLS 1.3 server sending a truncated PQC hybrid KeyShare can still trigger the error cleanup path to operate on freed memory. |
| Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, calling Document#encoding= with an invalid encoding (e.g., a non-string, or a string containing a null byte) raises an exception, but only after freeing the document's current encoding string without replacing it. The document is left referencing freed memory, so the next call to Document#encoding reads invalid memory, which can cause a segfault or leak freed bytes into a Ruby String. Affects the CRuby (libxml2) implementation only; JRuby is not affected. This vulnerability is fixed in 1.19.4. |
| Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri’s CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an XML attribute. If Ruby code had already accessed an attribute child node, Nokogiri::XML::Attr#value= could free the underlying native child node while the wrapper remained reachable through the document node cache. A later use of the freed child node or a Ruby GC mark could dereference an invalid pointer, causing an invalid read and a possible segfault. This vulnerability is fixed in 1.19.4. |
| Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::Document#root= validated only that the new root was a Nokogiri::XML::Node, allowing a DTD node to be set as the document root. The result is a heap use-after-free during garbage collection or finalization, leading to an invalid memory read or potentially a segfault. This vulnerability is fixed in 1.19.4. |
| Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::XPathContext did not keep its source document alive for garbage collection. If an XPathContext outlived its document and the document was collected, evaluating an XPath expression could read invalid memory and potentially segfault. This is only reachable when application code constructs an XPathContext directly and lets the document become unreachable while continuing to use the context. The normal Document#xpath, #css, and related search methods are not affected, and it is not triggerable by malicious document input. This vulnerability is fixed in 1.19.4. |
| Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, XInclude substitution performed by Nokogiri::XML::Node#do_xinclude replaced each <xi:include> in place, freeing the include node along with its children (such as <xi:fallback> and its descendants) and any namespaces declared on them. If an application had already exposed one of those nodes or namespaces to Ruby, the corresponding Ruby object was left pointing at freed memory. Using the object could result in invalid reads or writes to memory. This vulnerability is fixed in 1.19.4. |
| Use after free in Payments in Google Chrome on Android prior to 149.0.7827.201 allowed a local attacker to potentially exploit heap corruption via physical access to the device. (Chromium security severity: High) |
| In AzeoTech DAQFactory versions 21.1 and prior, a Use After Free vulnerability can be exploited by an attacker using specially crafted .ctl files which can result in code execution. |
| A use-after-free in the gf_filter_pid_get_packet function (/filter_core/filter_pid.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted media file. |
| In the Linux kernel, the following vulnerability has been resolved:
netdev: fix double-free in netdev_nl_bind_rx_doit()
Sashiko flags that genlmsg_reply() always consumes the skb.
The error path calls nlmsg_free(rsp) so we can't jump directly
to it. Let's not unbind, just propagate the error to the user.
This is the typical way of handling genlmsg_reply() failures.
They shouldn't happen unless user does something silly like
calling the kernel with an already-full rcvbuf. |
| In the Linux kernel, the following vulnerability has been resolved:
ptp: ocp: fix resource freeing order
Commit a60fc3294a37 ("ptp: rework ptp_clock_unregister() to disable
events") added a call to ptp_disable_all_events() which changes the
configuration of pins if they support EXTTS events. In ptp_ocp_detach()
pins resources are freed before ptp_clock_unregister() and it leads to
use-after-free during driver removal. Fix it by changing the order of
free/unregister calls. To avoid irq handler running on the other core
while ptp device unregistering, call synchronize_irq() after HW is
configured to stop producing irqs and no irqs are in-flight. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: rockchip: fix generic IRQ chip leak on remove
The driver allocates domain generic chips using
irq_alloc_domain_generic_chips() during probe. However, on driver
remove/teardown, the generic chips are not automatically freed when the
IRQ domain is removed because the domain flags do not include
IRQ_DOMAIN_FLAG_DESTROY_GC.
This causes both the domain generic chips structure and the associated
generic chips to be leaked. Additionally, the generic chips remain on
the global gc_list and may later be visited by generic IRQ chip suspend,
resume, or shutdown callbacks after the GPIO bank has been removed,
potentially resulting in a use-after-free and kernel crash.
Fix the resource leak by explicitly calling
irq_domain_remove_generic_chips() before removing the IRQ domain in
rockchip_gpio_remove(). |
| A use-after-free in the gf_filter_pid_inst_swap_delete_task function (/filter_core/filter_pid.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted media file. |
| A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure. |
| A use-after-free flaw was found in the X.Org X server and Xwayland in SyncChangeCounter(). A client that sets up multiple SyncCounters can trigger a use-after-free when destroying those counters via a second client connection while changing those counters. This may be used to crash the server, or for privilege escalation if the X server runs as root. |
| A use-after-free flaw was found in the X.Org X server and Xwayland in FreeCounter(). A client that sets up multiple SyncCounters and awaits on those triggers can trigger a use-after-free when destroying those counters via a second client connection. This may be used to crash the server, or for privilege escalation if the X server runs as root. |
| A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client that sets up multiple fence triggers can trigger a use-after-free function pointer call. An attacker would connect to the X server to set up a fence and await that fence, then a second X connection destroys the fence, causing the use-after-free. This may be used to crash the server, or for privilege escalation if the X server runs as root. |
| NSD from version 4.13.0 has a heap use-after-free bug in logging errors on TLS connections, causing a crash of the server process, which can be triggered trivially by sending a DNS query over a DoT connection, and closing the connection without reading the response. |
| sys/kern/sysv_sem.c in OpenBSD through 7.9 has a use-after-free allowing local privilege escalation to root. This is a context switch use-after-free after tsleep in sys_semget(). |
| Use after free in Blink in Google Chrome prior to 149.0.7827.197 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High) |
