https://notcve.org/view.php?id=CVE-2020-36781
In the Linux kernel, the following vulnerability has been resolved: i2c: imx: fix reference leak when pm_runtime_get_sync fails In i2c_imx_xfer() and i2c_imx_remove(), the pm reference count is not expected to be incremented on return. However, pm_runtime_get_sync will increment pm reference count even failed. Forgetting to putting operation will result in a reference leak here. Replace it with pm_runtime_resume_and_get to keep usage counter balanced. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: i2c: imx: corrige la fuga de referencia cuando falla pm_runtime_get_sync En i2c_imx_xfer() y i2c_imx_remove(), no se espera que el recuento de referencias pm aumente al regresar. Sin embargo, pm_runtime_get_sync incrementará el recuento de referencias de pm incluso si falla. Olvidarse de poner en funcionamiento resultará en una fuga de referencia aquí. • https://git.kernel.org/stable/c/3a5ee18d2a32bda6b9a1260136f6805848e3839d https://git.kernel.org/stable/c/3a0cdd336d92c429b51a79bf4f64b17eafa0325d https://git.kernel.org/stable/c/1ecc0ebc2ebbad4a22a670a07d27a21fa0b59c77 https://git.kernel.org/stable/c/ff406f6cd09c273337ab4854292e4aca48f8affd https://git.kernel.org/stable/c/47ff617217ca6a13194fcb35c6c3a0c57c080693 •

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2021-46974 – bpf: Fix masking negation logic upon negative dst register
https://notcve.org/view.php?id=CVE-2021-46974
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix masking negation logic upon negative dst register The negation logic for the case where the off_reg is sitting in the dst register is not correct given then we cannot just invert the add to a sub or vice versa. As a fix, perform the final bitwise and-op unconditionally into AX from the off_reg, then move the pointer from the src to dst and finally use AX as the source for the original pointer arithmetic operation such that the inversion yields a correct result. The single non-AX mov in between is possible given constant blinding is retaining it as it's not an immediate based operation. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bpf: corrige la lógica de negación de enmascaramiento en el registro dst negativo. La lógica de negación para el caso en el que off_reg se encuentra en el registro dst no es correcta, dado que entonces no podemos simplemente invertir la adición a un sub o viceversa. • https://git.kernel.org/stable/c/ae03b6b1c880a03d4771257336dc3bca156dd51b https://git.kernel.org/stable/c/f92a819b4cbef8c9527d9797110544b2055a4b96 https://git.kernel.org/stable/c/979d63d50c0c0f7bc537bf821e056cc9fe5abd38 https://git.kernel.org/stable/c/078da99d449f64ca04d459cdbdcce513b64173cd https://git.kernel.org/stable/c/4d542ddb88fb2f39bf7f14caa2902f3e8d06f6ba https://git.kernel.org/stable/c/0e2dfdc74a7f4036127356d42ea59388f153f42c https://git.kernel.org/stable/c/53e0db429b37a32b8fc706d0d90eb4583ad13848 https://git.kernel.org/stable/c/2cfa537674cd1051a3b8111536d77d055 •
