Network UPS Tools: A PWN Request in make-dist workflow can execute PR-controlled code with write-scoped GITHUB_TOKEN

Network UPS Tools is a collection of programs which provide a common interface for monitoring and administering UPS, PDU and SCD hardware. Prior to commits 658b24e and 1aa31d1, the GitHub Actions script used to prepare NUT tarballs and update GitHub Checks statuses and PR comments about it was mis-structured in terms of mixing code running with higher privileges (single-use token generated with write permissions) and untrusted inputs (PR source branch). A malicious PR run from a fork could extract the GITHUB_TOKEN value. It could potentially be abused while it was valid (while the GHA job ran) to manipulate Git repository contents, commit checks/statuses, or issue/PR comments, according to permissions it was issued with. This issue has been patched via commits 658b24e and 1aa31d1.

bpf: Reject resilient lock operations in rbtree callbacks

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject resilient lock operations in rbtree callbacks __bpf_rbtree_add() keeps parent and link pointers live across calls to the program-supplied comparison callback. The verifier therefore requires the root's lock to remain held throughout the callback. The helper path enforces this rule for bpf_spin_lock() and bpf_spin_unlock(), but the resilient lock kfunc argument path does not. Since resilient locks may protect BPF rbtree roots, a callback can release the root lock and let another CPU remove and free the node referenced by the in-progress tree walk. The walk then resumes using freed pointers. Reject resilient lock kfuncs in an rbtree comparison callback, matching the existing policy for the spin lock helpers. Resilient-lock-protected trees remain valid when their comparison callbacks leave lock state alone.

Zammad: Improper neutralization of `srcset` attribute in IMG tags in Zammad

Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2 and 7.1.0, zammad's HTML sanitizer (HtmlSanitizer::Strict) blocks external URLs in to prevent remote content loading, but the srcset attribute, also allowlisted for , is not subject to the same check. This oversight allows an attacker to embed arbitrary external URLs in the srcset attribute just by sending an e-mail, effectively bypassing the external content protection. When an agent views the ticket containing the malicious srcset, the browser will silently load the attacker-controlled URL, resulting in the leakage of the agent's IP address, User-Agent, Referer, and the exact time the ticket was viewed. HtmlSanitizer::Strict got extended to block external URLs in the srcset attribute of tags. This was done to prevent tracking pixels and external content loading, which could compromise user privacy. This issue is fixed in versions 7.0.2 and 7.1.0.

tracing: Don't dereference trace_event_file in deferred trigger free

In the Linux kernel, the following vulnerability has been resolved: tracing: Don't dereference trace_event_file in deferred trigger free The enable_event trigger defers trace_event_put_ref() to the trigger free kthread, but the trace_event_file can already be freed when the instance is removed. Keep the trace_event_call directly in enable_trigger_data so the deferred free does not access the freed trace_event_file.

Unauthenticated file read in Mikrotik RouterOS

RouterOS WebFig contains an unauthenticated file-read vulnerability in the /jsproxy path where a newly allocated session retains a stale uninitialized principal pointer used for file authorization. An unauthenticated attacker can prepare the allocator so that the file-serving path dereferences this pointer with sufficient rights, then supply parent-directory components in an encrypted URI to escape the WebFig file namespace and disclose root-owned files, including configuration stores containing credentials.This issue affects only 7.x branch was fixed in versions: 7.23.4 (Long-term) and 7.24.2 (Stable)

staging: octeon: add missing tasklet_kill in cvm_oct_tx_shutdown

In the Linux kernel, the following vulnerability has been resolved: staging: octeon: add missing tasklet_kill in cvm_oct_tx_shutdown The TX cleanup tasklet can be scheduled by the watchdog IRQ handler to execute cvm_oct_tx_do_cleanup. There can be a pending tasklet in the queue which might run after the cvm_oct_remove() frees net_device structures, causing a use-after-free in cvm_oct_tx_do_cleanup() as it iterates cvm_oct_device[] which is an array of netdevice pointers. Add tasklet_kill() after free_irq() to ensure the tasklet is no longer scheduled or running before teardown proceeds.

RDMA/bnxt_re: Validate udata before executing commands

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Validate udata before executing commands The destroy callbacks currently zero the udata output after tearing down driver resources. If the userspace access fails, uverbs preserves the uobject and allows the destroy callback to run again, even though the driver resource has already been freed. Call ib_no_udata_io() before teardown so udata failures are detected while the resource is still intact, then return success after teardown completes. As part of this change, move ib_respond_empty_udata() to the start of the create and modify flows. While this is not strictly required for general create flows, as the core layer unwinds uobjects on failure, it is necessary for create AH. In _rdma_create_ah(), the HW object is otherwise leaked.

NetBox Device Type Library: PR-controllable upstream clone URL (NETBOX_DT_LIBRARY_URL) enables SSRF and test-data substitution from CI

NetBox Device Type Library is a collection of community-sourced device type definitions for import into NetBox. In the affected repository revisions, NETBOX_DT_LIBRARY_URL in tests/test_configuration.py is a free-form tracked constant that an unauthenticated pull-request author can change before the validation test harness runs. During pytest collection, tests/definitions_test.py passes the value to Repo.clone_from and create_remote("upstream").fetch(), causing blind Git smart-HTTP requests to an attacker-selected host or loading attacker-controlled tests/known-*.json validation caches. The blind request cannot set arbitrary metadata-service headers or return response bodies, and this path does not execute remote Git hooks, but substituted known data can bypass slug, module, and rack uniqueness validation. This vulnerability is fixed in commit 8980c690097e92f5028c7e6df402b327d827ecd5.

Kiro IDE Allows Agentic Writes to Global Configurations While Working in Untrusted Workspaces

The file write tool in Amazon Kiro IDE versions before 1.0.242 might allow remote unauthenticated actors to inject crafted instructions into the agent's context. When a user runs the agent in a crafted repository as an untrusted workspace, sending any message can cause agent modifications to auto-loaded global configuration paths. We recommend you upgrade to Kiro IDE version 1.0.242 or later. Users who ran the agent in an untrusted workspace on an earlier version should also review the global Kiro configuration directory (~/.kiro) for entries they did not create.

irqchip/renesas-irqc: Fix generic interrupt chip leak on remove

In the Linux kernel, the following vulnerability has been resolved: irqchip/renesas-irqc: Fix generic interrupt chip leak on remove The driver allocates domain generic chips probe. However, on driver removal, the generic chips are not automatically freed when the interrupt 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 list and may later be accessed by generic interrupt chip suspend, resume, or shutdown callbacks after the driver has been removed, potentially resulting in a use-after-free and kernel crash. Fix the resource leak by setting IRQ_DOMAIN_FLAG_DESTROY_GC on the interrupt domain; this lets the interrupt domain core automatically release all generic chips when irq_domain_remove() is invoked, removing the need for manual cleanup calls in error paths and remove callback.

Use-after-free in DoQ stream output buffer on reset re-transmission

NLnet Labs Unbound 1.22.0 up to and including 1.26.1, has a use-after-free vulnerability when compiled for DNS-over-QUIC support with '--with-libngtcp2'. Each DoQ stream owns an output buffer that holds the DNS response. ngtcp2's retransmission buffer keeps a shallow pointer into the output buffer for as long as a STREAM frame may be resent. On a client RESET_STREAM, the output buffer is freed but ngtcp2 still holds the matching retransmission entries. The next PTO timeout makes ngtcp2 re-encode the STREAM frame and copy from the freed buffer. A malicious actor that can query Unbound over DoQ and that withholds ACKs, sends RESET_STREAM, and waits for PTO, reaches this use-after-free with no privilege. This leads to retransmissions against freed memory and eventually an abnormal server exit under a 20-query spray.

Use-after-free in DoH stream cleanup code path

NLnet Labs Unbound 1.12.0 up to and including 1.26.0 has a use-after-free vulnerability when compiled for DNS-over-HTTPs support with '--with-libnghttp2'. During failure code paths (i.e., RPZ drop query, jostle due to heavy traffic), a dropped DoH stream brings down the whole DoH session and does not account properly for other DoH streams in the same session. This leads to use-after-free in those code paths. If the prerequisites are satisfied (possible RPZ drop or heavy client traffic), a malicious actor can trigger the vulnerability with a single DoH connection and the appropriate traffic. Impact is limited as the reads are not user controlled and the use-after-free leads to early returns. However, a hardened allocator can catch the use-after-free and controllably terminate the process resulting to denial of service.
