sigwire

sigwire tail -f シグナル用。 マシン上の任意のプロセスが発生させるすべてのシグナル — 誰が送ったか、誰が受けたか、どのシグナルか、どのように発生したか（kill2、カーネル、POSIX タイマー）、ターゲットがそれを捕捉したかどうかとハンドラの実行時間、ブロックされたシステムコールを EINTR で引き裂いたかどうか — カーネルのシグナルトレースポイントからデコードし、ライブで端末にストリーミングします。1つのPIDに strace -f する必要も、ptrace も、関係するプロセスからの協力も不要です。 sigwire...

ltm

ltm Linux用のマシンヒストリーデバッガー。eBPFを介してプロセス、ファイル、ネットワーク、メモリ、ブロックI/Oを記録し、メタデータをSQLiteに保存し、そのマシンで何が起こったかについてのタイムライン/差分/平易な英語/SQLの質問に答えます。 ⚠️ 現在はトレースポイントのみのキャプチャ — 現在の記録はトレースポイントプログラムを使用しています。まだkprobes、uprobes、XDP、TCフックは使用していません。そのため、より深いカーネル内部、ユーザースペース関数トレーシング、パケットパス検査よりも、安定したシステムコール/ブロック/プロセスメタデータを優先します。...

CVE-2026-98062

In the Linux kernel, the following vulnerability has been resolved: bpf: Mark signal tracepoint siginfo arguments as scalar The signalgenerate and signaldeliver tracepoints declare their info argument as a struct kernelsiginfo pointer. btfctxaccess therefore treats it as a trusted pointer for tpb...

CVE-2026-98062

A flaw in the Linux kernel's BPF subsystem allows a local user with privileges to attach BPF programs to exploit a memory handling issue. The kernel incorrectly treats siginfo arguments in the signal_generate and signal_deliver tracepoints as trusted memory pointers. However, these tracepoints ca...

CVE-2026-93287: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: i2c: smbus: reject oversized block transfers in the common path The SMBus block transfer length data-block0 is validated in i2csmbusxferemulated but that check runs too late for tracepoints and is skipped entirely when the adapte...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: IB/mad: Do not call to functions that might sleep while in atomic context. Tracepoints are not allowed to sleep. As a result, the following error is generated due to a call to ibquerypkey in atomic context. WARNING: CPU: 0 PID:...

CVE-2026-89702: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: size fhverify server sockaddr slot by xptlocallen The nfsdfhverify and nfsdfhverifyerr tracepoints declare the server sockaddr slot sized by xptremotelen but fill it from xptlocal using xptlocallen: TPSTRUCTentry...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098992 advisory. In the Linux kernel, the following vulnerability has been resolved: btrfs: tracepoints: get correct superblock from dentry in event btrfssyncfile If overlay is used ...

SUSE CVE-2026-74418

In the Linux kernel, the following vulnerability has been resolved: dma-fence: Fix potential tracepoint null pointer dereferences Tracedmafencesignaled, tracedmafencewaitend and tracedmafencedestroy can all currently dereference a null fence-ops pointer after it has been reset on fence signalling...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: dma-fence: Fixed the potential issue of dereferencing a null pointer in tracedmafinesignaled, tracedmafinewaitend, and tracedmafinedestroy. After the fence signalling is reset, a null fence-ops pointer may be dereferenced. We...

Unity Linux 20.1050e Security Update: kernel (UTSA-2026-102056)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-102056 advisory.

CVE-2026-74490

In the Linux kernel, the following vulnerability has been resolved: tipc: avoid use-after-free in poll trace queue dumps TIPC socket tracepoints dump queue state through tipcskdump. Most queue-dump callsites already serialize that walk under the socket lock or sk-sklock.slock, but tipcpoll calls...

CVE-2026-72299

CVE-2026-72299 affects the Linux kernel's TIPC code path. The issue arises when tipc_sk_enqueue() runs with sk_lock held in user context and the TIPC_DUMP_ALL tracepoints dump sk_receive_queue, risking dereferencing skbs that the socket owner has already dequeued or freed. The fix limits the unsa...
