CVE-2021-47149 – net: fujitsu: fix potential null-ptr-deref
https://notcve.org/view.php?id=CVE-2021-47149
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: netfilter: nf_tables: disallow timeout for anonymous sets Never used from userspace, disallow these parameters. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nf_tables: no permite el tiempo de espera para conjuntos anónimos Nunca se usa desde el espacio de usuario, no permita estos parámetros. A vulnerability was found in netfilter/nf_tables componets of Linux Kernel allows an userspace to set timeouts for anonymous sets, which are not intended to be used this way. This could lead to unexpected behaviour or security issues. • https://git.kernel.org/stable/c/116b0e8e4673a5faa8a739a19b467010c4d3058c https://git.kernel.org/stable/c/49ce99ae43314d887153e07cec8bb6a647a19268 https://git.kernel.org/stable/c/6f3ae02bbb62f151b19162d5fdc9fe3d48450323 https://git.kernel.org/stable/c/00b19ee0dcc1aef06294471ab489bae26d94524e https://git.kernel.org/stable/c/b7be6c737a179a76901c872f6b4c1d00552d9a1b https://git.kernel.org/stable/c/e26d3009efda338f19016df4175f354a9bd0a4ab https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html https://lists.debian.org/debian-lts-announce/2024 • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •
