https://notcve.org/view.php?id=CVE-2021-47159
In the Linux kernel, the following vulnerability has been resolved: net: dsa: fix a crash if ->get_sset_count() fails If ds->ops->get_sset_count() fails then it "count" is a negative error code such as -EOPNOTSUPP. Because "i" is an unsigned int, the negative error code is type promoted to a very high value and the loop will corrupt memory until the system crashes. Fix this by checking for error codes and changing the type of "i" to just int. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: dsa: corrige un bloqueo si ->get_sset_count() falla. Si ds->ops->get_sset_count() falla, entonces "count" es un código de error negativo como - EOPNOTSUPP. Debido a que "i" es un int sin signo, el código de error negativo se promociona a un valor muy alto y el bucle corromperá la memoria hasta que el sistema falle. • https://git.kernel.org/stable/c/badf3ada60ab8f76f9488dc8f5c0c57f70682f5a https://git.kernel.org/stable/c/0f2cb08c57edefb0e7b5045e0e3e9980a3d3aa37 https://git.kernel.org/stable/c/ce5355f140a7987011388c7e30c4f8fbe180d3e8 https://git.kernel.org/stable/c/caff86f85512b8e0d9830e8b8b0dfe13c68ce5b6 https://git.kernel.org/stable/c/7b22466648a4f8e3e94f57ca428d1531866d1373 https://git.kernel.org/stable/c/a269333fa5c0c8e53c92b5a28a6076a28cde3e83 •

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 •

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 •
