https://notcve.org/view.php?id=CVE-2020-36784
In the Linux kernel, the following vulnerability has been resolved: i2c: cadence: fix reference leak when pm_runtime_get_sync fails The PM reference count is not expected to be incremented on return in functions cdns_i2c_master_xfer and cdns_reg_slave. However, pm_runtime_get_sync will increment pm usage counter 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: cadencia: corrige la fuga de referencia cuando falla pm_runtime_get_sync No se espera que el recuento de referencias de PM aumente al regresar en las funciones cdns_i2c_master_xfer y cdns_reg_slave. Sin embargo, pm_runtime_get_sync incrementará el contador de uso de pm incluso si falla. Olvidarse de poner en funcionamiento resultará en una fuga de referencia aquí. • https://git.kernel.org/stable/c/7fa32329ca03148fb2c07b4ef3247b8fc0488d6a https://git.kernel.org/stable/c/30410519328c94367e561fd878e5f0d3a0303585 https://git.kernel.org/stable/c/d57ff04e0ed6f3be1682ae861ead33f879225e07 https://git.kernel.org/stable/c/a45fc41beed8e0fe31864619c34aa00797fb60c1 https://git.kernel.org/stable/c/23ceb8462dc6f4b4decdb5536a7e5fc477cdf0b6 •

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 •
