In the Linux kernel, the following vulnerability has been resolved: net: fujitsu: fix potential null-ptr-deref In fmvj18x_get_hwinfo(), if ioremap fails there will be NULL pointer deref. To fix this, check the return value of ioremap and return -1 to the caller in case of failure. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: fujitsu: corrige el potencial null-ptr-deref En fmvj18x_get_hwinfo(), si ioremap falla, habrá un puntero NULL deref. Para solucionar este problema, verifique el valor de retorno de ioremap y devuelva -1 a la persona que llama en caso de falla. • https://git.kernel.org/stable/c/b92170e209f7746ed72eaac98f2c2f4b9af734e6 https://git.kernel.org/stable/c/6dbf1101594f7c76990b63c35b5a40205a914b6b https://git.kernel.org/stable/c/c4f1c23edbe921ab2ecd6140d700e756cd44c5f7 https://git.kernel.org/stable/c/7883d3895d0fbb0ba9bff0f8665f99974b45210f https://git.kernel.org/stable/c/22049c3d40f08facd1867548716a484dad6b3251 https://git.kernel.org/stable/c/71723a796ab7881f491d663c6cd94b29be5fba50 https://git.kernel.org/stable/c/f14bf57a08779a5dee9936f63ada0149ea89c5e6 https://git.kernel.org/stable/c/52202be1cd996cde6e8969a128dc27ee4 •

In the Linux kernel, the following vulnerability has been resolved: ptp: ocp: Fix a resource leak in an error handling path If an error occurs after a successful 'pci_ioremap_bar()' call, it must be undone by a corresponding 'pci_iounmap()' call, as already done in the remove function. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ptp: ocp: corrige una fuga de recursos en una ruta de manejo de errores. Si se produce un error después de una llamada exitosa a 'pci_ioremap_bar()', se debe deshacer mediante el correspondiente 'pci_iounmap()' 'llamar, como ya se hizo en la función de eliminación. • https://git.kernel.org/stable/c/a7e1abad13f3f0366ee625831fecda2b603cdc17 https://git.kernel.org/stable/c/0e38e702f1152479e6afac34f151dbfd99417f99 https://git.kernel.org/stable/c/9c1bb37f8cad5e2ee1933fa1da9a6baa7876a8e4 •
