Releases 20.04 LTS --------------------------------------------------------------------------------- Open side navigation Packages o linux-nvidia-tegra-5.15 - Linux kernel for NVIDIA Tegra systems Details Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: o ARM64 architecture; o Block layer subsystem; o Cryptographic API; o Drivers core; o Bluetooth drivers; o DMA engine subsystem; o GPU drivers; o HID subsystem; o Intel Trace Hub HW tracing drivers; o IIO ADC drivers; o IRQ chip drivers; o Modular ISDN driver; o LED subsystem; o UACCE accelerator framework; o Ethernet bonding driver; o Network drivers; o STMicroelectronics network drivers; o Ethernet team driver; o NVME drivers; o PHY drivers; o SLIMbus drivers; o W1 Dallas's 1-wire bus driver; o Xen hypervisor drivers; o BTRFS file system; o Ext4 file system; o Network file system (NFS) client; o Network file system (NFS) server daemon; o NTFS3 file system; o SMB network file system; o NFC subsystem; o BPF subsystem; o IRQ subsystem; o Memory management; o Bluetooth subsystem; o CAN network layer; o Networking core; o IPv4 networking; o IPv6 networking; o L2TP protocol; o Netfilter; o NET/ROM layer; o Network traffic control; o SCTP protocol; o TLS protocol; o XFRM subsystem; o Creative Sound Blaster X-Fi driver; o USB sound devices --------------------------------------------------------------------------------- Update instructions ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. The problem can be corrected by updating your system to the following package versions: Ubuntu Package Version Release linux-image-5.15.0-1057-nvidia-tegra - 5.15.0-1057.57~20.04.1 Ubuntu Pro Fix available with Ubuntu Pro . linux-image-5.15.0-1057-nvidia-tegra-rt - 5.15.0-1057.57~20.04.1 Ubuntu Pro Fix available with Ubuntu Pro . linux-image-nvidia-tegra - 5.15.0.1057.57~20.04.1 Ubuntu Pro Fix 20.04 LTS available with Ubuntu Pro . focal linux-image-nvidia-tegra-5.15 - 5.15.0.1057.57~20.04.1 Ubuntu Pro Fix available with Ubuntu Pro . linux-image-nvidia-tegra-rt - 5.15.0.1057.57~20.04.1 Ubuntu Pro Fix available with Ubuntu Pro . linux-image-nvidia-tegra-rt-5.15 - 5.15.0.1057.57~20.04.1 Ubuntu Pro Fix available with Ubuntu Pro . --------------------------------------------------------------------------------- References o CVE-2026-23209 o CVE-2026-23170 o CVE-2026-23167 o CVE-2026-23164 o CVE-2026-23150 o CVE-2026-23146 o CVE-2026-23145 o CVE-2026-23133 o CVE-2026-23128 o CVE-2026-23125 o CVE-2026-23124 o CVE-2026-23121 o CVE-2026-23120 o CVE-2026-23119 o CVE-2026-23111 o CVE-2026-23108 o CVE-2026-23105 o CVE-2026-23103 o CVE-2026-23101 o CVE-2026-23099 o CVE-2026-23098 o CVE-2026-23097 o CVE-2026-23096 o CVE-2026-23095 o CVE-2026-23093 o CVE-2026-23091 o CVE-2026-23090 o CVE-2026-23089 o CVE-2026-23087 o CVE-2026-23085 o CVE-2026-23084 o CVE-2026-23083 o CVE-2026-23080 o CVE-2026-23078 o CVE-2026-23076 o CVE-2026-23075 o CVE-2026-23074 o CVE-2026-23073 o CVE-2026-23071 o CVE-2026-23064 o CVE-2026-23063 o CVE-2026-23061 o CVE-2026-23060 o CVE-2026-23058 o CVE-2026-23056 o CVE-2026-23049 o CVE-2026-23038 o CVE-2026-23037 o CVE-2026-23033 o CVE-2026-23026 o CVE-2026-23011 o CVE-2026-23003 o CVE-2026-23001 o CVE-2026-22999 o CVE-2026-22998 o CVE-2026-22997 o CVE-2025-71199 o CVE-2025-71197 o CVE-2025-71196 o CVE-2025-71194 o CVE-2025-71191 o CVE-2025-71190 o CVE-2025-71188 o CVE-2025-71186 o CVE-2025-71185 o CVE-2025-71163 o CVE-2025-71080 o CVE-2025-68817 o CVE-2025-68725 o CVE-2025-68365 o CVE-2025-68340 o CVE-2025-68211 o CVE-2025-40164 o CVE-2025-40149 o CVE-2025-38591 o CVE-2025-38408 o CVE-2025-38232 o CVE-2025-38125 o CVE-2025-38057 o CVE-2025-37849 o CVE-2023-54207 o CVE-2023-53662 o CVE-2023-53520 o CVE-2023-53421 --------------------------------------------------------------------------------- Related notices o USN-8163-1 o USN-8159-1 o USN-8159-2 o USN-8159-3 o USN-8152-1 o USN-8149-1 o USN-8149-2 o USN-8148-1 o USN-8148-2 o USN-8148-3 o USN-8148-4 o USN-8148-5 o USN-8145-1 o USN-8145-2 o USN-8145-3 o USN-8143-1 o USN-8143-2 o USN-8142-1 o USN-8126-1 o USN-8125-1 o USN-8100-1 o USN-8095-1 o USN-8095-2 o USN-8095-3 o USN-8095-4 o USN-8095-5 o USN-8094-5 o USN-8094-1 o USN-8094-2 o USN-8094-3 o USN-8094-4 o USN-8074-1 o USN-8074-2 o USN-8052-1 o USN-8052-2 o USN-8048-1 o USN-8031-1 o USN-8031-2 o USN-8031-3 o USN-8030-1 o USN-8029-1 o USN-8029-2 o USN-8029-3 o USN-8028-1 o USN-8028-2 o USN-8028-3 o USN-8028-4 o USN-8028-5 o USN-8028-6 o USN-8028-7 o USN-8028-8 o USN-7856-1 o USN-7834-1 o USN-7833-1 o USN-7833-2 o USN-7833-3 o USN-7833-4 o USN-7789-1 o USN-7789-2 o USN-7771-1 o USN-7770-1 o USN-7769-1 o USN-7769-2 o USN-7769-3 o USN-7594-1 o USN-7594-2 o USN-7594-3 --------------------------------------------------------------------------------- - --------------------------END INCLUDED TEXT---------------------- You have received this e-mail bulletin as a result of your organisation's registration with AUSCERT.
