Oct 28, 2026Joker is a small Clojure interpreter, linter and formatter written in Go.CVE-2026-59172 · Other software · candid82 · reported by GitHubHigh 7.8
Joker is a small Clojure interpreter, linter and formatter written in Go. Prior to 1.8.2, `joker --lint <file>` walks upward from the linted file to locate a `.jokerd/` directory and executes matching `linter.*` files before linting. Those files contain executable Joker/Clojure code, so linting a file inside an untrusted repository can execute repository-supplied code with the linter user's privileges. Editor integrations and CI jobs that automatically lint checked-out source can trigger this behavior. The patch stops executing project-local linter customizations and loads executable customization only from the user's home directory. This issue is fixed in version 1.8.2.

Oct 28, 2026Allocation of Resources Without Limits or Throttling vulnerability in the HTTP/2 request body reader of mtrudel bandit allows an unauthenticated remote attackerCVE-2026-116078 · Other software · mtrudel · reported by 6b3ad84c-e1a6-4bf7-a703-f496b71e49dbHigh 8.7
Allocation of Resources Without Limits or Throttling vulnerability in the HTTP/2 request body reader of mtrudel bandit allows an unauthenticated remote attacker to exhaust server memory via a request body sent as many 1-byte DATA frames. do_read_data/5 in lib/bandit/http2/stream.ex keeps every DATA frame payload as its own list element until the read returns. The :length option of read_body/2 counts body bytes, not frames, so a body of 1-byte frames costs a list cell and a binary term per byte. Interleaving the frames across up to 500 concurrent streams per connection keeps each stream consuming its frames as they arrive; in the reporter's test, 100 streams held 25 to 40 MiB of stream process memory for 5 MB sent. Only routes whose Plug reads the request body are affected, which includes any route behind Plug.Parsers. This issue affects bandit: from 0.3.1 before 1.14.1.

Oct 28, 2026In the Linux kernel, the following vulnerability has been resolved: firewire: core: fix race condition in split transaction handling For a split transaction, CVE-2026-99185 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: firewire: core: fix race condition in split transaction handling For a split transaction, either fw_core_handle_response() or split_transaction_timeout_callback() may manipulate the same transaction entry in the pending transaction list. The return value of timer_delete() is used to determine which function handles the entry. If the transaction is a split transaction and timer_delete() returns zero, the timeout callback may already be running. In this case, the response handler must leave the entry in the list for the timeout callback to remove. A previous code refactoring broke this behavior, introducing a race condition in which both functions could process the same transaction. This could lead to a use-after-free on the transaction initiator side. Fix the regression by ensuring that the response handler does not process the transaction when timer_delete() returns zero. The timeout callback is responsible for removing the entry from the pending transaction list.

Oct 28, 2026In the Linux kernel, the following vulnerability has been resolved: dm-crypt: fix a tiny race condition in crypt_dec_pending crypt_dec_pending reads io->errorCVE-2026-99136 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: dm-crypt: fix a tiny race condition in crypt_dec_pending crypt_dec_pending reads io->error before calling atomic_dec_and_test. Another context, for example crypt_endio called from an interrupt, may set io->error and drop its reference between the read and the decrement. crypt_dec_pending then drops the last reference and completes the bio with the stale status - so a read that failed and was never decrypted, or a write that failed, is reported as successful. The read was placed before the decrement by commit b35f8caa0890 ("dm crypt: wait for endio to complete before destruction"), because that commit freed dm_crypt_io before calling bio_endio. This is no longer the case, dm_crypt_io lives in the per-bio data now. Read io->error after atomic_dec_and_test instead. atomic_dec_and_test is fully ordered, so no additional barrier is needed.

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: actually validate userq BOs This was supposed to loop over the individual evicted list, as the kernel and always_valid evicted lists were already handled in amdgpu_vm_validate. Without this, BOs that were created and evicted before a userq was made would never end up in an eviction fence rearm. Also add the missing ref to the BO before drm_exec locks and refs it.

The mechanism binding files generated during a shredding process to the authentication method is not working correctly and the same session token is used for all token-based API users. This is similar to an issue fixed in 2026.7.1 but was missed while creating the fix. Since the files are referred to by randomly generated UUIDs and only exist for a day, there is virtually no risk, but it renders the added protection mechanism useless. As part of the fix, we have also improved hardening of some other related code areas.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
