Add a cleanup path.

CVSS: 5.2EPSS: 0%CPEs: 8EXPL: 0CVE-2021-47153 – i2c: i801: Don't generate an interrupt on bus reset
https://notcve.org/view.php?id=CVE-2021-47153
In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Don't generate an interrupt on bus reset Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt handler (i801_isr) is not prepared for this situation and will try to process the interrupt as if it was signaling the end of a successful transaction. In the case of a block transaction, this can result in an out-of-range memory access. This condition was reproduced several times by syzbot: https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e https://syzkaller.appspot.com/bug? • https://git.kernel.org/stable/c/636752bcb5177a301d0266270661581de8624828 https://git.kernel.org/stable/c/f9469082126cebb7337db3992d143f5e4edfe629 https://git.kernel.org/stable/c/09c9e79f4c10cfb6b9e0e1b4dd355232e4b5a3b3 https://git.kernel.org/stable/c/dfa8929e117b0228a7765f5c3f5988a4a028f3c6 https://git.kernel.org/stable/c/c70e1ba2e7e65255a0ce004f531dd90dada97a8c https://git.kernel.org/stable/c/04cc05e3716ae31b17ecdab7bc55c8170def1b8b https://git.kernel.org/stable/c/b523feb7e8e44652f92f3babb953a976e7ccbbef https://git.kernel.org/stable/c/1f583d3813f204449037cd2acbfc09168 • CWE-125: Out-of-bounds Read •
CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2021-47152 – mptcp: fix data stream corruption
https://notcve.org/view.php?id=CVE-2021-47152
In the Linux kernel, the following vulnerability has been resolved: mptcp: fix data stream corruption Maxim reported several issues when forcing a TCP transparent proxy to use the MPTCP protocol for the inbound connections. He also provided a clean reproducer. The problem boils down to 'mptcp_frag_can_collapse_to()' assuming that only MPTCP will use the given page_frag. If others - e.g. the plain TCP protocol - allocate page fragments, we can end-up re-using already allocated memory for mptcp_data_frag. Fix the issue ensuring that the to-be-expanded data fragment is located at the current page frag end. v1 -> v2: - added missing fixes tag (Mat) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: mptcp: corrige la corrupción del flujo de datos Maxim informó varios problemas al forzar a un proxy transparente TCP a utilizar el protocolo MPTCP para las conexiones entrantes. También proporcionó un reproductor limpio. El problema se reduce a 'mptcp_frag_can_collapse_to()' suponiendo que sólo MPTCP utilizará el page_frag dado. Si otros (por ejemplo, el protocolo TCP simple) asignan fragmentos de página, podemos terminar reutilizando la memoria ya asignada para mptcp_data_frag. • https://git.kernel.org/stable/c/18b683bff89d46ace55f12d00c0440d44d6160c4 https://git.kernel.org/stable/c/3267a061096efc91eda52c2a0c61ba76e46e4b34 https://git.kernel.org/stable/c/18e7f0580da15cac1e79d73683ada5a9e70980f8 https://git.kernel.org/stable/c/29249eac5225429b898f278230a6ca2baa1ae154 •
